<p>This function is intended for runtime reconfiguration of filters on traces
|
||||
when the filter recalculation is much less frequent than trace events are.
|
||||
The alternative is to have the <a href="../subscriber/trait.Subscriber.html"><code>Subscriber</code></a> that supports runtime
|
||||
reconfiguration of filters always return <a href="../subscriber/struct.Interest.html#method.sometimes"><code>Interest::sometimes()</code></a> so that
|
||||
<a href="../subscriber/trait.Subscriber.html#tymethod.enabled"><code>enabled</code></a> is evaluated for every event.</p>
|
||||
<p>This function will also re-compute the global maximum level as determined by
|
||||
the <a href="../subscriber/trait.Subscriber.html#method.max_level_hint"><code>max_level_hint</code></a> method. If a <a href="../subscriber/trait.Subscriber.html"><code>Subscriber</code></a>
|
||||
implementation changes the value returned by its <code>max_level_hint</code>
|
||||
implementation at runtime, then it <strong>must</strong> call this function after that
|
||||
value changes, in order for the change to be reflected.</p>

|
||||
<p>The <em>dispatcher</em> is the component of the tracing system which is responsible
|
||||
for forwarding trace data from the instrumentation points that generate it
|
||||
to the subscriber that collects it.</p>
|
||||
<h1 id="using-the-trace-dispatcher" class="section-header"><a href="#using-the-trace-dispatcher">Using the Trace Dispatcher</a></h1>
|
||||
<p>Every thread in a program using <code>tracing</code> has a <em>default subscriber</em>. When
|
||||
events occur, or spans are created, they are dispatched to the thread’s
|
||||
current subscriber.</p>
|
||||
<h2 id="setting-the-default-subscriber" class="section-header"><a href="#setting-the-default-subscriber">Setting the Default Subscriber</a></h2>
|
||||
<p>By default, the current subscriber is an empty implementation that does
|
||||
nothing. To use a subscriber implementation, it must be set as the default.
|
||||
There are two methods for doing so: <a href="fn.with_default.html"><code>with_default</code></a> and
|
||||
<a href="fn.set_global_default.html"><code>set_global_default</code></a>. <code>with_default</code> sets the default subscriber for the
|
||||
duration of a scope, while <code>set_global_default</code> sets a default subscriber
|
||||
for the entire process.</p>
|
||||
<p>To use either of these functions, we must first wrap our subscriber in a
|
||||
<a href="struct.Dispatch.html"><code>Dispatch</code></a>, a cloneable, type-erased reference to a subscriber. For
|
||||
example:</p>
|
||||
|
||||
<div class="example-wrap"><pre class="rust rust-example-rendered">
|
||||
<span class="kw">use</span> <span class="ident">dispatcher</span>::<span class="ident">Dispatch</span>;
|
||||
|
||||
<span class="kw">let</span> <span class="ident">my_subscriber</span> <span class="op">=</span> <span class="ident">FooSubscriber</span>::<span class="ident">new</span>();
|
||||
<span class="kw">let</span> <span class="ident">my_dispatch</span> <span class="op">=</span> <span class="ident">Dispatch</span>::<span class="ident">new</span>(<span class="ident">my_subscriber</span>);</pre></div>
|
||||
<p>Then, we can use <a href="fn.with_default.html"><code>with_default</code></a> to set our <code>Dispatch</code> as the default for
|
||||
the duration of a block:</p>
|
||||
|
||||
<div class="example-wrap"><pre class="rust rust-example-rendered">
|
||||
<span class="comment">// no default subscriber</span>
|
||||
|
||||
<span class="ident">dispatcher</span>::<span class="ident">with_default</span>(<span class="kw-2">&</span><span class="ident">my_dispatch</span>, <span class="op">|</span><span class="op">|</span> {
|
||||
<span class="comment">// my_subscriber is the default</span>
|
||||
});
|
||||
|
||||
<span class="comment">// no default subscriber again</span></pre></div>
|
||||
<p>It’s important to note that <code>with_default</code> will not propagate the current
|
||||
thread’s default subscriber to any threads spawned within the <code>with_default</code>
|
||||
block. To propagate the default subscriber to new threads, either use
|
||||
<code>with_default</code> from the new thread, or use <code>set_global_default</code>.</p>
|
||||
<p>As an alternative to <code>with_default</code>, we can use <a href="fn.set_global_default.html"><code>set_global_default</code></a> to
|
||||
set a <code>Dispatch</code> as the default for all threads, for the lifetime of the
|
||||
program. For example:</p>
|
||||
|
||||
<div class="example-wrap"><pre class="rust rust-example-rendered">
|
||||
<span class="comment">// no default subscriber</span>
|
||||
|
||||
<span class="ident">dispatcher</span>::<span class="ident">set_global_default</span>(<span class="ident">my_dispatch</span>)
|
||||
<span class="comment">// `set_global_default` will return an error if the global default</span>
|
||||
<span class="comment">// subscriber has already been set.</span>
|
||||
.<span class="ident">expect</span>(<span class="string">"global default was already set!"</span>);
|
||||
|
||||
<span class="comment">// `my_subscriber` is now the default</span></pre></div>
|
||||
<div class="information">
|
||||
<div class="tooltip ignore" style="">ⓘ<span class="tooltiptext">Note</span></div>

execution of a program.</p>
|
||||
<p>An <code>Event</code> can be compared to a log record in unstructured logging, but with
|
||||
two key differences:</p>
|
||||
<ul>
|
||||
<li><code>Event</code>s exist <em>within the context of a <a href="../span">span</a></em>. Unlike log lines, they
|
||||
may be located within the trace tree, allowing visibility into the
|
||||
<em>temporal</em> context in which the event occurred, as well as the source
|
||||
code location.</li>
|
||||
<li>Like spans, <code>Event</code>s have structured key-value data known as <em><a href="../field">fields</a></em>,
|
||||
which may include textual message. In general, a majority of the data
|
||||
associated with an event should be in the event’s fields rather than in
|
||||
the textual message, as the fields are more structured.</li>

|

<p>Spans and events may be annotated with key-value data, referred to as known
|
||||
as <em>fields</em>. These fields consist of a mapping from a key (corresponding to
|
||||
a <code>&str</code> but represented internally as an array index) to a <a href="trait.Value.html"><code>Value</code></a>.</p>
|
||||
<h1 id="values-and-subscribers" class="section-header"><a href="#values-and-subscribers"><code>Value</code>s and <code>Subscriber</code>s</a></h1>
|
||||
<p><code>Subscriber</code>s consume <code>Value</code>s as fields attached to <a href="../span/">span</a>s or <a href="../event/struct.Event.html"><code>Event</code></a>s.
|
||||
The set of field keys on a given span or is defined on its <a href="../metadata/struct.Metadata.html"><code>Metadata</code></a>.
|
||||
When a span is created, it provides <a href="../span/struct.Attributes.html"><code>Attributes</code></a> to the <code>Subscriber</code>’s
|
||||
<a href="../subscriber/trait.Subscriber.html#method.new_span"><code>new_span</code></a> method, containing any fields whose values were provided when
|
||||
the span was created; and may call the <code>Subscriber</code>’s <a href="../span/struct.Record.html"><code>record</code></a> method
|
||||
with additional <a href="../span/struct.Record.html"><code>Record</code></a>s if values are added for more of its fields.
|
||||
Similarly, the <a href="../event/struct.Event.html"><code>Event</code></a> type passed to the subscriber’s <a href="../event/struct.Event.html"><code>event</code></a> method
|
||||
will contain any fields attached to each event.</p>
|

<p><code>tracing</code> represents values as either one of a set of Rust primitives
|
||||
(<code>i64</code>, <code>u64</code>, <code>bool</code>, and <code>&str</code>) or using a <code>fmt::Display</code> or <code>fmt::Debug</code>
|
||||
implementation. <code>Subscriber</code>s are provided these primitive value types as
|
||||
<code>dyn Value</code> trait objects.</p>
|
||||
<p>These trait objects can be formatted using <code>fmt::Debug</code>, but may also be
|
||||
recorded as typed data by calling the <a href="trait.Value.html#method.record"><code>Value::record</code></a> method on these
|
||||
trait objects with a <em>visitor</em> implementing the <a href="trait.Visit.html"><code>Visit</code></a> trait. This trait
|
||||
represents the behavior used to record values of various types. For example,
|
||||
we might record integers by incrementing counters for their field names,
|
||||
rather than printing them.</p>

of those callsites are not equivalent.

|

<p>An instance of <code>Visit</code> (“a visitor”) represents the logic necessary to
|
||||
record field values of various types. When an implementor of <a href="trait.Value.html"><code>Value</code></a> is
|
||||
<a href="trait.Value.html#method.record">recorded</a>, it calls the appropriate method on the provided visitor to
|
||||
indicate the type that value should be recorded as.</p>
|
||||
<p>When a <a href="../subscriber/trait.Subscriber.html"><code>Subscriber</code></a> implementation <a href="../subscriber/trait.Subscriber.html#method.event">records an <code>Event</code></a> or a
|
||||
<a href="../subscriber/trait.Subscriber.html#method.record">set of <code>Value</code>s added to a <code>Span</code></a>, it can pass an <code>&mut Visit</code> to the
|
||||
<code>record</code> method on the provided <a href="struct.ValueSet.html"><code>ValueSet</code></a> or <a href="../event/struct.Event.html"><code>Event</code></a>. This visitor
|
||||
will then be used to record all the field-value pairs present on that
|
||||
<code>Event</code> or <code>ValueSet</code>.</p>

<h1 id="examples" class="section-header"><a href="#examples">Examples</a></h1>

<p>A simple visitor that writes to a string might be implemented like so:</p>

<p>This visitor will format each recorded value using <code>fmt::Debug</code>, and
|
||||
append the field name and formatted value to the provided string,
|
||||
regardless of the type of the recorded value. When all the values have
|
||||
been recorded, the <code>StringVisitor</code> may be dropped, allowing the string
|
||||
to be printed or stored in some other data structure.</p>
|
||||
<p>The <code>Visit</code> trait provides default implementations for <code>record_i64</code>,
|
||||
<code>record_u64</code>, <code>record_bool</code>, <code>record_str</code>, and <code>record_error</code>, which simply
|
||||
forward the recorded value to <code>record_debug</code>. Thus, <code>record_debug</code> is the
|
||||
only method which a <code>Visit</code> implementation <em>must</em> implement. However,
|
||||
visitors may override the default implementations of these functions in
|
||||
order to implement type-specific behavior.</p>
|
||||
<p>Additionally, when a visitor receives a value of a type it does not care
|
||||
about, it is free to ignore those values completely. For example, a
|
||||
visitor which only records numeric data might look like this:</p>

<p>This visitor (which is probably not particularly useful) keeps a running

sum of all the numeric values it records, and ignores all other values. A

more practical example of recording typed values is presented in

<code>examples/counters.rs</code>, which demonstrates a very simple metrics system

implemented using <code>tracing</code>.</p>

|
||||
<p><a href="https://crates.io/crates/tracing"><code>tracing</code></a> is a framework for instrumenting Rust programs to collect
|
||||
structured, event-based diagnostic information. This crate defines the core
|
||||
primitives of <code>tracing</code>.</p>
|
||||
<p>This crate provides:</p>
|
||||
<ul>
|
||||
<li>
|
||||
<p><a href="span/struct.Id.html"><code>span::Id</code></a> identifies a span within the execution of a program.</p>
|
||||
</li>
|
||||
<li>
|
||||
<p><a href="event/struct.Event.html"><code>Event</code></a> represents a single event within a trace.</p>
|
||||
</li>
|
||||
<li>
|
||||
<p><a href="subscriber/trait.Subscriber.html"><code>Subscriber</code></a>, the trait implemented to collect trace data.</p>
|
||||
</li>
|
||||
<li>
|
||||
<p><a href="metadata/struct.Metadata.html"><code>Metadata</code></a> and <a href="callsite/trait.Callsite.html"><code>Callsite</code></a> provide information describing spans and
|
||||
<code>Event</code>s.</p>
|
||||
</li>
|
||||
<li>
|
||||
<p><a href="field/struct.Field.html"><code>Field</code></a>, <a href="field/struct.FieldSet.html"><code>FieldSet</code></a>, <a href="field/trait.Value.html"><code>Value</code></a>, and <a href="field/struct.ValueSet.html"><code>ValueSet</code></a> represent the
|
||||
structured data attached to a span.</p>
|
||||
</li>
|
||||
<li>
|
||||
<p><a href="dispatcher/struct.Dispatch.html"><code>Dispatch</code></a> allows spans and events to be dispatched to <code>Subscriber</code>s.</p>
|
||||
</li>
|
||||
</ul>
|
||||
<p>In addition, it defines the global callsite registry and per-thread current
|
||||
dispatcher which other components of the tracing system rely on.</p>
|
||||
<p><em>Compiler support: <a href="#supported-rust-versions">requires <code>rustc</code> 1.40+</a></em></p>
|
||||
<h2 id="usage" class="section-header"><a href="#usage">Usage</a></h2>
|
||||
<p>Application authors will typically not use this crate directly. Instead,
|
||||
they will use the <a href="https://crates.io/crates/tracing"><code>tracing</code></a> crate, which provides a much more
|
||||
fully-featured API. However, this crate’s API will change very infrequently,
|
||||
so it may be used when dependencies must be very stable.</p>
|
||||
<p><code>Subscriber</code> implementations may depend on <code>tracing-core</code> rather than
|
||||
<code>tracing</code>, as the additional APIs provided by <code>tracing</code> are primarily useful
|
||||
for instrumenting libraries and applications, and are generally not
|
||||
necessary for <code>Subscriber</code> implementations.</p>
|
||||
<p>The <a href="https://github.com/tokio-rs/tracing"><code>tokio-rs/tracing</code></a> repository contains less stable crates designed to
|
||||
be used with the <code>tracing</code> ecosystem. It includes a collection of
|
||||
<code>Subscriber</code> implementations, as well as utility and adapter crates.</p>
|
||||
<h3 id="crate-feature-flags" class="section-header"><a href="#crate-feature-flags">Crate Feature Flags</a></h3>
|
||||
<p>The following crate feature flags are available:</p>
|
||||
<ul>
|
||||
<li>
|
||||
<p><code>std</code>: Depend on the Rust standard library (enabled by default).</p>
|
||||
<p><code>no_std</code> users may disable this feature with <code>default-features = false</code>:</p>
|
||||
<pre><code class="language-toml">[dependencies]
|
||||
tracing-core = { version = "0.1.17", default-features = false }
|
||||
</code></pre>
|
||||
<p><strong>Note</strong>:<code>tracing-core</code>’s <code>no_std</code> support requires <code>liballoc</code>.</p>
|
||||
</li>
|
||||
</ul>
|
||||
<h2 id="supported-rust-versions" class="section-header"><a href="#supported-rust-versions">Supported Rust Versions</a></h2>
|
||||
<p>Tracing is built against the latest stable release. The minimum supported
|
||||
version is 1.40. The current Tracing version is not guaranteed to build on
|
||||
Rust versions earlier than the minimum supported version.</p>
|
||||
<p>Tracing follows the same compiler support policies as the rest of the Tokio
|
||||
project. The current stable Rust compiler and the three most recent minor
|
||||
versions before it will always be supported. For example, if the current
|
||||
stable compiler version is 1.45, the minimum supported version will not be
|
||||
increased past 1.42, three minor versions prior. Increasing the minimum
|
||||
supported compiler version is not considered a semver breaking change as
|
||||
long as doing so complies with this policy.</p>

|
||||
<p>All spans and events have the following metadata:</p>
|
||||
<ul>
|
||||
<li>A <a href="#method.name">name</a>, represented as a static string.</li>
|
||||
<li>A <a href="#method.target">target</a>, a string that categorizes part of the system where the span
|
||||
or event occurred. The <code>tracing</code> macros default to using the module
|
||||
path where the span or event originated as the target, but it may be
|
||||
overridden.</li>
|
||||
<li>A <a href="#method.level">verbosity level</a>.</li>
|
||||
<li>The names of the <a href="#method.fields">fields</a> defined by the span or event.</li>
|
||||
<li>Whether the metadata corresponds to a span or event.</li>
|
||||
</ul>
|
||||
<p>In addition, the following optional metadata describing the source code
|
||||
location where the span or event originated <em>may</em> be provided:</p>
|
||||
<ul>
|
||||
<li>The <a href="#method.file">file name</a></li>
|
||||
<li>The <a href="#method.line">line number</a></li>
|
||||
<li>The <a href="#method.module">module path</a></li>
|
||||
</ul>
|
||||
<p>Metadata is used by <a href="../subscriber/trait.Subscriber.html"><code>Subscriber</code></a>s when filtering spans and events, and it
|
||||
may also be used as part of their data payload.</p>
|
||||
<p>When created by the <code>event!</code> or <code>span!</code> macro, the metadata describing a
|
||||
particular event or span is constructed statically and exists as a single
|
||||
static instance. Thus, the overhead of creating the metadata is
|
||||
<em>significantly</em> lower than that of creating the actual span. Therefore,
|
||||
filtering is based on metadata, rather than on the constructed span.</p>

<strong>Note</strong>: Although instances of <code>Metadata</code> cannot

be compared directly, they provide a method <a href="struct.Metadata.html#method.id">

the same callsite.

execution of a program.</p>
|
||||
<p>An <code>Event</code> can be compared to a log record in unstructured logging, but with
|
||||
two key differences:</p>
|
||||
<ul>
|
||||
<li><code>Event</code>s exist <em>within the context of a <a href="../span">span</a></em>. Unlike log lines, they
|
||||
may be located within the trace tree, allowing visibility into the
|
||||
<em>temporal</em> context in which the event occurred, as well as the source
|
||||
code location.</li>
|
||||
<li>Like spans, <code>Event</code>s have structured key-value data known as <em><a href="../field">fields</a></em>,
|
||||
which may include textual message. In general, a majority of the data
|
||||
associated with an event should be in the event’s fields rather than in
|
||||
the textual message, as the fields are more structured.</li>

|
||||
<p>All spans and events have the following metadata:</p>
|
||||
<ul>
|
||||
<li>A <a href="#method.name">name</a>, represented as a static string.</li>
|
||||
<li>A <a href="#method.target">target</a>, a string that categorizes part of the system where the span
|
||||
or event occurred. The <code>tracing</code> macros default to using the module
|
||||
path where the span or event originated as the target, but it may be
|
||||
overridden.</li>
|
||||
<li>A <a href="#method.level">verbosity level</a>.</li>
|
||||
<li>The names of the <a href="#method.fields">fields</a> defined by the span or event.</li>
|
||||
<li>Whether the metadata corresponds to a span or event.</li>
|
||||
</ul>
|
||||
<p>In addition, the following optional metadata describing the source code
|
||||
location where the span or event originated <em>may</em> be provided:</p>
|
||||
<ul>
|
||||
<li>The <a href="#method.file">file name</a></li>
|
||||
<li>The <a href="#method.line">line number</a></li>
|
||||
<li>The <a href="#method.module">module path</a></li>
|
||||
</ul>
|
||||
<p>Metadata is used by <a href="../subscriber/trait.Subscriber.html"><code>Subscriber</code></a>s when filtering spans and events, and it
|
||||
may also be used as part of their data payload.</p>
|
||||
<p>When created by the <code>event!</code> or <code>span!</code> macro, the metadata describing a
|
||||
particular event or span is constructed statically and exists as a single
|
||||
static instance. Thus, the overhead of creating the metadata is
|
||||
<em>significantly</em> lower than that of creating the actual span. Therefore,
|
||||
filtering is based on metadata, rather than on the constructed span.</p>

}</pre></div><div class="docblock"><p>Trait representing the functions required to collect trace data.</p>
|
||||
<p>Crates that provide implementations of methods for collecting or recording
|
||||
trace data should implement the <code>Subscriber</code> interface. This trait is
|
||||
intended to represent fundamental primitives for collecting trace events and
|
||||
spans — other libraries may offer utility functions and types to make
|
||||
subscriber implementations more modular or improve the ergonomics of writing
|
||||
subscribers.</p>
|
||||
<p>A subscriber is responsible for the following:</p>
|
||||
<ul>
|
||||
<li>Registering new spans as they are created, and providing them with span
|
||||
IDs. Implicitly, this means the subscriber may determine the strategy for
|
||||
determining span equality.</li>
|
||||
<li>Recording the attachment of field values and follows-from annotations to
|
||||
spans.</li>
|
||||
<li>Filtering spans and events, and determining when those filters must be
|
||||
invalidated.</li>
|
||||
<li>Observing spans as they are entered, exited, and closed, and events as
|
||||
they occur.</li>
|
||||
</ul>
|
||||
<p>When a span is entered or exited, the subscriber is provided only with the
|
||||
<a href="../span/struct.Id.html">ID</a> with which it tagged that span when it was created. This means
|
||||
that it is up to the subscriber to determine whether and how span <em>data</em> —
|
||||
the fields and metadata describing the span — should be stored. The
|
||||
<a href="trait.Subscriber.html#method.new_span"><code>new_span</code></a> function is called when a new span is created, and at that
|
||||
point, the subscriber <em>may</em> choose to store the associated data if it will
|
||||
be referenced again. However, if the data has already been recorded and will
|
||||
not be needed by the implementations of <code>enter</code> and <code>exit</code>, the subscriber
|
||||
may freely discard that data without allocating space to store it.</p>
|
||||
<h2 id="overriding-default-impls" class="section-header"><a href="#overriding-default-impls">Overriding default impls</a></h2>
|
||||
<p>Some trait methods on <code>Subscriber</code> have default implementations, either in
|
||||
order to reduce the surface area of implementing <code>Subscriber</code>, or for
|
||||
backward-compatibility reasons. However, many subscribers will likely want
|
||||
to override these default implementations.</p>
|
||||
<p>The following methods are likely of interest:</p>
|
||||
<ul>
|
||||
<li><a href="trait.Subscriber.html#method.register_callsite"><code>register_callsite</code></a> is called once for each callsite from which a span
|
||||
event may originate, and returns an <a href="struct.Interest.html"><code>Interest</code></a> value describing whether or
|
||||
not the subscriber wishes to see events or spans from that callsite. By
|
||||
default, it calls <a href="trait.Subscriber.html#method.enabled"><code>enabled</code></a>, and returns <code>Interest::always()</code> if
|
||||
<code>enabled</code> returns true, or <code>Interest::never()</code> if enabled returns false.
|
||||
However, if the subscriber’s interest can change dynamically at runtime,
|
||||
it may want to override this function to return <code>Interest::sometimes()</code>.
|
||||
Additionally, subscribers which wish to perform a behaviour once for each
|
||||
callsite, such as allocating storage for data related to that callsite,
|
||||
can perform it in <code>register_callsite</code>.</li>
|
||||
<li><a href="trait.Subscriber.html#method.clone_span"><code>clone_span</code></a> is called every time a span ID is cloned, and <a href="trait.Subscriber.html#method.try_close"><code>try_close</code></a>
|
||||
is called when a span ID is dropped. By default, these functions do
|
||||
nothing. However, they can be used to implement reference counting for
|
||||
spans, allowing subscribers to free storage for span data and to determine
|
||||
when a span has <em>closed</em> permanently (rather than being exited).
|
||||
Subscribers which store per-span data or which need to track span closures
|
||||
should override these functions together.</li>
|
||||
</ul>

<p>By default, it is assumed that this filter needs only be evaluated once
|
||||
for each callsite, so it is called by <a href="#method.register_callsite"><code>register_callsite</code></a> when each

primarily as an optimization, so that expensive filters (such as those

|

<p>However, if the subscriber’s interest in a particular span or event may

then the <code>register_callsite</code> method should be overridden to return

<p>IDs are used to uniquely identify spans and events within the context of a

subscriber, so span equality will be based on the returned ID. Thus, if

<p>This function is guaranteed to be called at least once per callsite on

never be enabled unless a new subscriber expresses interest in it.</p>

will be called every time an event or span is created from that callsite.</p>
|

<p>For example, suppose a sampling subscriber is implemented by

incrementing a counter every time <code>enabled</code> is called and only returning
|
||||
<code>true</code> when the counter is divisible by a specified sampling rate. If
|
||||
that subscriber returns <code>Interest::always</code> from <code>register_callsite</code>, then
|

the filter will not be re-evaluated once it has been applied to a given

set of metadata. Thus, the counter will not be incremented, and the span
|
||||
or event that corresponds to the metadata will never be <code>enabled</code>.</p>
|
||||
<p><code>Subscriber</code>s that need to change their filters occasionally should call
|
||||
<a href="../callsite/fn.rebuild_interest_cache.html"><code>rebuild_interest_cache</code></a> to re-evaluate <code>register_callsite</code> for all
|

callsites.</p>
|
||||
<p>Similarly, if a <code>Subscriber</code> has a filtering strategy that can be

changed dynamically at runtime, it would need to re-evaluate that filter
|
||||
if the cached results have changed.</p>
|
||||
<p>A subscriber which manages fanout to multiple other subscribers
|
||||
should proxy this decision to all of its child subscribers,
|
||||
returning <code>Interest::never</code> only if <em>all</em> such children return
|
||||
<code>Interest::never</code>. If the set of subscribers to which spans are
|
||||
broadcast may change dynamically, the subscriber should also never
|
||||
return <code>Interest::Never</code>, as a new subscriber may be added that <em>is</em>
|
||||
interested.</p>

<h1 id="notes" class="section-header"><a href="#notes">Notes</a></h1>

<p>This function may be called again when a new subscriber is created or

this method, it is responsible for ensuring that

<p>This API is required for <code>downcast_raw</code> to be a trait method; a method

|

<p>This method may be overridden by “fan out” or “chained” subscriber

|
||||
<p>Crates that provide implementations of methods for collecting or recording
|
||||
trace data should implement the <code>Subscriber</code> interface. This trait is
|
||||
intended to represent fundamental primitives for collecting trace events and
|
||||
spans — other libraries may offer utility functions and types to make
|
||||
subscriber implementations more modular or improve the ergonomics of writing
|
||||
subscribers.</p>
|
||||
<p>A subscriber is responsible for the following:</p>
|
||||
<ul>
|
||||
<li>Registering new spans as they are created, and providing them with span
|
||||
IDs. Implicitly, this means the subscriber may determine the strategy for
|
||||
determining span equality.</li>
|
||||
<li>Recording the attachment of field values and follows-from annotations to
|
||||
spans.</li>
|
||||
<li>Filtering spans and events, and determining when those filters must be
|
||||
invalidated.</li>
|
||||
<li>Observing spans as they are entered, exited, and closed, and events as
|
||||
they occur.</li>
|
||||
</ul>
|
||||
<p>When a span is entered or exited, the subscriber is provided only with the
|
||||
<a href="../span/struct.Id.html">ID</a> with which it tagged that span when it was created. This means
|
||||
that it is up to the subscriber to determine whether and how span <em>data</em> —
|
||||
the fields and metadata describing the span — should be stored. The
|
||||
<a href="trait.Subscriber.html#method.new_span"><code>new_span</code></a> function is called when a new span is created, and at that
|
||||
point, the subscriber <em>may</em> choose to store the associated data if it will
|
||||
be referenced again. However, if the data has already been recorded and will
|
||||
not be needed by the implementations of <code>enter</code> and <code>exit</code>, the subscriber
|
||||
may freely discard that data without allocating space to store it.</p>
|
||||
<h2 id="overriding-default-impls" class="section-header"><a href="#overriding-default-impls">Overriding default impls</a></h2>
|
||||
<p>Some trait methods on <code>Subscriber</code> have default implementations, either in
|
||||
order to reduce the surface area of implementing <code>Subscriber</code>, or for
|
||||
backward-compatibility reasons. However, many subscribers will likely want
|
||||
to override these default implementations.</p>
|
||||
<p>The following methods are likely of interest:</p>
|
||||
<ul>
|
||||
<li><a href="trait.Subscriber.html#method.register_callsite"><code>register_callsite</code></a> is called once for each callsite from which a span
|
||||
event may originate, and returns an <a href="struct.Interest.html"><code>Interest</code></a> value describing whether or
|
||||
not the subscriber wishes to see events or spans from that callsite. By
|
||||
default, it calls <a href="trait.Subscriber.html#method.enabled"><code>enabled</code></a>, and returns <code>Interest::always()</code> if
|
||||
<code>enabled</code> returns true, or <code>Interest::never()</code> if enabled returns false.
|
||||
However, if the subscriber’s interest can change dynamically at runtime,
|
||||
it may want to override this function to return <code>Interest::sometimes()</code>.
|
||||
Additionally, subscribers which wish to perform a behaviour once for each
|
||||
callsite, such as allocating storage for data related to that callsite,
|
||||
can perform it in <code>register_callsite</code>.</li>
|
||||
<li><a href="trait.Subscriber.html#method.clone_span"><code>clone_span</code></a> is called every time a span ID is cloned, and <a href="trait.Subscriber.html#method.try_close"><code>try_close</code></a>
|
||||
is called when a span ID is dropped. By default, these functions do
|
||||
nothing. However, they can be used to implement reference counting for
|
||||
spans, allowing subscribers to free storage for span data and to determine
|
||||
when a span has <em>closed</em> permanently (rather than being exited).
|
||||
Subscribers which store per-span data or which need to track span closures
|
||||
should override these functions together.</li>
|
||||
</ul>

<p>By default, it is assumed that this filter needs only be evaluated once
|
||||
for each callsite, so it is called by <a href="#method.register_callsite"><code>register_callsite</code></a> when each

primarily as an optimization, so that expensive filters (such as those

|
||||
<p>However, if the subscriber’s interest in a particular span or event may

|

then the <code>register_callsite</code> method should be overridden to return

<p>IDs are used to uniquely identify spans and events within the context of a

<p>This function is guaranteed to be called at least once per callsite on

wishes to be notified about the callsite, and its filter need not be

never be enabled unless a new subscriber expresses interest in it.</p>

will be called every time an event or span is created from that callsite.</p>
|
||||
<p>For example, suppose a sampling subscriber is implemented by
|

incrementing a counter every time <code>enabled</code> is called and only returning
|
||||
<code>true</code> when the counter is divisible by a specified sampling rate. If
|
||||
that subscriber returns <code>Interest::always</code> from <code>register_callsite</code>, then
|
||||
the filter will not be re-evaluated once it has been applied to a given
|
||||
set of metadata. Thus, the counter will not be incremented, and the span
|
||||
or event that corresponds to the metadata will never be <code>enabled</code>.</p>
|
||||
<p><code>Subscriber</code>s that need to change their filters occasionally should call
|
||||
<a href="../callsite/fn.rebuild_interest_cache.html"><code>rebuild_interest_cache</code></a> to re-evaluate <code>register_callsite</code> for all
|

callsites.</p>
|
||||
<p>Similarly, if a <code>Subscriber</code> has a filtering strategy that can be

changed dynamically at runtime, it would need to re-evaluate that filter
|
||||
if the cached results have changed.</p>
|
||||
<p>A subscriber which manages fanout to multiple other subscribers
|
||||
should proxy this decision to all of its child subscribers,
|
||||
returning <code>Interest::never</code> only if <em>all</em> such children return
|
||||
<code>Interest::never</code>. If the set of subscribers to which spans are
|
||||
broadcast may change dynamically, the subscriber should also never
|
||||
return <code>Interest::Never</code>, as a new subscriber may be added that <em>is</em>
|

interested.</p>

<p>Higher-level libraries providing functionality for composing multiple

subscriber implementations may use this return value to notify any

“layered” subscribers that this subscriber considers the span closed.</p>
|
||||
<p>The default implementation of this method calls the subscriber’s
|
||||
<a href="trait.Subscriber.html#method.drop_span"><code>drop_span</code></a> method and returns <code>false</code>. This means that, unless the
|
||||
subscriber overrides the default implementation, close notifications
|
||||
will never be sent to any layered subscribers. In general, if the
|
||||
subscriber tracks reference counts, this method should be implemented,
|
||||
rather than <code>drop_span</code>.</p>
|
||||
<p>This function is guaranteed to only be called with span IDs that were
|
||||
returned by this subscriber’s <code>new_span</code> function.</p>
|
||||
<p>It’s guaranteed that if this function has been called once more than the
|
||||
number of times <code>clone_span</code> was called with the same <code>id</code>, then no more
|
||||
handles that can enter the span with that <code>id</code> exist. This means that it
|
||||
can be used in conjunction with <a href="trait.Subscriber.html#method.clone_span"><code>clone_span</code></a> to track the number of
|
||||
handles capable of <code>enter</code>ing a span. When all the handles have been
|
||||
dropped (i.e., <code>try_close</code> has been called one more time than
|
||||
<code>clone_span</code> for a given ID), the subscriber may assume that the span
|
||||
will not be entered again, and should return <code>true</code>. It is then free to
|
||||
deallocate storage for data associated with that span, write data from
|
||||
that span to IO, and so on.</p>
|
||||
<p><strong>Note</strong>: since this function is called when spans are dropped,
|
||||
implementations should ensure that they are unwind-safe. Panicking from
|
||||
inside of a <code>try_close</code> function may cause a double panic, if the span
|
||||
was dropped due to a thread unwinding.</p>

<p>If you wish to downcast a <code>Subscriber</code>, it is strongly advised to use

the safe API provided by <a href="#method.downcast_ref"><code>downcast_ref</code></a> instead.</p>
|

<p>This API is required for <code>downcast_raw</code> to be a trait method; a method
|

signature like <a href="#method.downcast_ref"><code>downcast_ref</code></a> (with a generic type parameter) is not
|

object-safe, and thus cannot be a trait method for <code>Subscriber</code>. This
|
||||
means that if we only exposed <code>downcast_ref</code>, <code>Subscriber</code>
|
||||
implementations could not override the downcasting behavior</p>
|
||||
<p>This method may be overridden by “fan out” or “chained” subscriber
|
||||
implementations which consist of multiple composed types. Such
|
||||
subscribers might allow <code>downcast_raw</code> by returning references to those

component if they contain components with the given <code>TypeId</code>.</p>

<h1 id="safety" class="section-header"><a href="#safety">Safety</a></h1>
|

<p>The <a href="#method.downcast_ref"><code>downcast_ref</code></a> method expects that the pointer returned by

<code>downcast_raw</code> is non-null and points to a valid instance of the type
|
||||
with the provided <code>TypeId</code>. Failure to ensure this will result in
|
||||
undefined behaviour, so implementing <code>downcast_raw</code> is unsafe.</p>
