|
||
<p><code>Notify</code> provides a basic mechanism to notify a single task of an event.
|
||
<code>Notify</code> itself does not carry any data. Instead, it is to be used to signal
|
||
another task to perform an operation.</p>
|
||
<p><code>Notify</code> can be thought of as a <a href="../../tokio/sync/struct.Semaphore.html"><code>Semaphore</code></a> starting with 0 permits.
|
||
<a href="../../tokio/sync/struct.Notify.html#method.notified"><code>notified().await</code></a> waits for a permit to become available, and <a href="../../tokio/sync/struct.Notify.html#method.notify_one"><code>notify_one()</code></a>
|
||
sets a permit <strong>if there currently are no available permits</strong>.</p>
|
||
<p>The synchronization details of <code>Notify</code> are similar to
|
||
<a href="https://doc.rust-lang.org/nightly/std/thread/fn.park.html"><code>thread::park</code></a> and <a href="https://doc.rust-lang.org/nightly/std/thread/struct.Thread.html#method.unpark"><code>Thread::unpark</code></a> from std. A <a href="../../tokio/sync/struct.Notify.html" title="Notify"><code>Notify</code></a>
|
||
value contains a single permit. <a href="../../tokio/sync/struct.Notify.html#method.notified"><code>notified().await</code></a> waits for the permit to
|
||
be made available, consumes the permit, and resumes. <a href="../../tokio/sync/struct.Notify.html#method.notify_one"><code>notify_one()</code></a> sets the
|
||
permit, waking a pending task if there is one.</p>
|
||
<p>If <code>notify_one()</code> is called <strong>before</strong> <code>notified().await</code>, then the next call to
|
||
<code>notified().await</code> will complete immediately, consuming the permit. Any
|
||
subsequent calls to <code>notified().await</code> will wait for a new permit.</p>
|
||
<p>If <code>notify_one()</code> is called <strong>multiple</strong> times before <code>notified().await</code>, only a
|
||
<strong>single</strong> permit is stored. The next call to <code>notified().await</code> will
|
||
complete immediately, but the one after will wait for a new permit.</p>
