wakeups from calls to <a href="../struct.Notify.html#method.notify_one" title="method tokio::sync::Notify::notify_one"><code>notify_one</code></a>.</p>
<p>Polling the future also adds it to the list, so this method should only
be used if you want to add the future to the list before the first call
to <code>poll</code>. (In fact, this method is equivalent to calling <code>poll</code> except
that no <code>Waker</code> is registered.)</p>
<p>This has no effect on notifications sent using <a href="../struct.Notify.html#method.notify_waiters" title="method tokio::sync::Notify::notify_waiters"><code>notify_waiters</code></a>, which
are received as long as they happen after the creation of the <code>Notified</code>
regardless of whether <code>enable</code> or <code>poll</code> has been called.</p>
<p>This method returns true if the <code>Notified</code> is ready. This happens in the
following situations:</p>
<ol>
<li>The <code>notify_waiters</code> method was called between the creation of the
<code>Notified</code> and the call to this method.</li>
<li>This is the first call to <code>enable</code> or <code>poll</code> on this future, and the
<code>Notify</code> was holding a permit from a previous call to <code>notify_one</code>.
The call consumes the permit in that case.</li>
<li>The future has previously been enabled or polled, and it has since
then been marked ready by either consuming a permit from the
<code>Notify</code>, or by a call to <code>notify_one</code> or <code>notify_waiters</code> that
removed it from the list of futures ready to receive wakeups.</li>
</ol>
<p>If this method returns true, any future calls to poll on the same future
will immediately return <code>Poll::Ready</code>.</p>
<h5 id="examples"><a class="doc-anchor" href="#examples">§</a>Examples</h5>
<p>Unbound multi-producer multi-consumer (mpmc) channel.</p>
<p>The call to <code>enable</code> is important because otherwise if you have two
calls to <code>recv</code> and two calls to <code>send</code> in parallel, the following could
happen:</p>
<ol>
<li>Both calls to <code>try_recv</code> return <code>None</code>.</li>
<li>Both new elements are added to the vector.</li>
<li>The <code>notify_one</code> method is called twice, adding only a single
permit to the <code>Notify</code>.</li>
<li>Both calls to <code>recv</code> reach the <code>Notified</code> future. One of them
consumes the permit, and the other sleeps forever.</li>
</ol>
<p>By adding the <code>Notified</code> futures to the list by calling <code>enable</code> before
<code>try_recv</code>, the <code>notify_one</code> calls in step three would remove the
futures from the list and mark them notified instead of adding a permit
to the <code>Notify</code>. This ensures that both futures are woken.</p>
