Each sent value is seen by
|
||||
all consumers.</p>
|
||||
<p>A <a href="../../../tokio/sync/broadcast/struct.Sender.html"><code>Sender</code></a> is used to broadcast values to <strong>all</strong> connected <a href="../../../tokio/sync/broadcast/struct.Receiver.html"><code>Receiver</code></a>
|
||||
values. <a href="../../../tokio/sync/broadcast/struct.Sender.html"><code>Sender</code></a> handles are clone-able, allowing concurrent send and
|
||||
receive actions. <a href="../../../tokio/sync/broadcast/struct.Sender.html"><code>Sender</code></a> and <a href="../../../tokio/sync/broadcast/struct.Receiver.html"><code>Receiver</code></a> are both <code>Send</code> and <code>Sync</code> as
|
||||
long as <code>T</code> is also <code>Send</code> or <code>Sync</code> respectively.</p>
|
||||
<p>When a value is sent, <strong>all</strong> <a href="../../../tokio/sync/broadcast/struct.Receiver.html"><code>Receiver</code></a> handles are notified and will
|
||||
receive the value. The value is stored once inside the channel and cloned on
|
||||
demand for each receiver. Once all receivers have received a clone of the
|
||||
value, the value is released from the channel.</p>
|
||||
<p>A channel is created by calling <a href="../../../tokio/sync/broadcast/fn.channel.html"><code>channel</code></a>, specifying the maximum number
|
||||
of messages the channel can retain at any given time.</p>
|
||||
<p>New <a href="../../../tokio/sync/broadcast/struct.Receiver.html"><code>Receiver</code></a> handles are created by calling <a href="../../../tokio/sync/broadcast/struct.Sender.html#method.subscribe"><code>Sender::subscribe</code></a>. The
|
||||
returned <a href="../../../tokio/sync/broadcast/struct.Receiver.html"><code>Receiver</code></a> will receive values sent <strong>after</strong> the call to
|
||||
<code>subscribe</code>.</p>
|
||||
<h2 id="lagging" class="section-header"><a href="#lagging">Lagging</a></h2>
|
||||
<p>As sent messages must be retained until <strong>all</strong> <a href="../../../tokio/sync/broadcast/struct.Receiver.html"><code>Receiver</code></a> handles receive
|
||||
a clone, broadcast channels are susceptible to the “slow receiver” problem.
|
||||
In this case, all but one receiver are able to receive values at the rate
|
||||
they are sent. Because one receiver is stalled, the channel starts to fill
|
||||
up.</p>
|
||||
<p>This broadcast channel implementation handles this case by setting a hard
|
||||
upper bound on the number of values the channel may retain at any given
|
||||
time. This upper bound is passed to the <a href="../../../tokio/sync/broadcast/fn.channel.html"><code>channel</code></a> function as an argument.</p>
|
||||
<p>If a value is sent when the channel is at capacity, the oldest value
|
||||
currently held by the channel is released. This frees up space for the new
|
||||
value. Any receiver that has not yet seen the released value will return
|
||||
<a href="../../../tokio/sync/broadcast/error/enum.RecvError.html#variant.Lagged"><code>RecvError::Lagged</code></a> the next time <a href="../../../tokio/sync/broadcast/struct.Receiver.html#method.recv"><code>recv</code></a> is called.</p>
|
||||
<p>Once <a href="../../../tokio/sync/broadcast/error/enum.RecvError.html#variant.Lagged"><code>RecvError::Lagged</code></a> is returned, the lagging receiver’s position is
|
||||
updated to the oldest value contained by the channel. The next call to
|
||||
<a href="../../../tokio/sync/broadcast/struct.Receiver.html#method.recv"><code>recv</code></a> will return this value.</p>
|
||||
<p>This behavior enables a receiver to detect when it has lagged so far behind
|
||||
that data has been dropped. The caller may decide how to respond to this:
|
||||
either by aborting its task or by tolerating lost messages and resuming
|
||||
consumption of the channel.</p>
|
||||
<h2 id="closing" class="section-header"><a href="#closing">Closing</a></h2>
|
||||
<p>When <strong>all</strong> <a href="../../../tokio/sync/broadcast/struct.Sender.html"><code>Sender</code></a> handles have been dropped, no new values may be
|
||||
sent. At this point, the channel is “closed”. Once a receiver has received
|
||||
all values retained by the channel, the next call to <a href="../../../tokio/sync/broadcast/struct.Receiver.html#method.recv"><code>recv</code></a> will return
|
||||
with <a href="../../../tokio/sync/broadcast/error/enum.RecvError.html#variant.Closed"><code>RecvError::Closed</code></a>.</p>
