the current task for wakeup if the value is not yet available.</p>
<h5 id="return-value"><a href="#return-value">Return value</a></h5>
<p>This function returns:</p>
<ul>
<li><a href="../../task/enum.Poll.html#variant.Pending" title="Poll::Pending"><code>Poll::Pending</code></a> if the future is not ready yet</li>
<li><a href="../../task/enum.Poll.html#variant.Ready"><code>Poll::Ready(val)</code></a> with the result <code>val</code> of this future if it
finished successfully.</li>
</ul>
<p>Once a future has finished, clients should not <code>poll</code> it again.</p>
<p>When a future is not ready yet, <code>poll</code> returns <code>Poll::Pending</code> and
stores a clone of the <a href="../../task/struct.Waker.html"><code>Waker</code></a> copied from the current <a href="../../task/struct.Context.html" title="Context"><code>Context</code></a>.
This <a href="../../task/struct.Waker.html"><code>Waker</code></a> is then woken once the future can make progress.
For example, a future waiting for a socket to become
readable would call <code>.clone()</code> on the <a href="../../task/struct.Waker.html"><code>Waker</code></a> and store it.
When a signal arrives elsewhere indicating that the socket is readable,
<a href="../../task/struct.Waker.html#method.wake"><code>Waker::wake</code></a> is called and the socket future’s task is awoken.
Once a task has been woken up, it should attempt to <code>poll</code> the future
again, which may or may not produce a final value.</p>
<p>Note that on multiple calls to <code>poll</code>, only the <a href="../../task/struct.Waker.html"><code>Waker</code></a> from the
<a href="../../task/struct.Context.html" title="Context"><code>Context</code></a> passed to the most recent call should be scheduled to
receive a wakeup.</p>
<h5 id="runtime-characteristics"><a href="#runtime-characteristics">Runtime characteristics</a></h5>
<p>Futures alone are <em>inert</em>; they must be <em>actively</em> <code>poll</code>ed to make
progress, meaning that each time the current task is woken up, it should
actively re-<code>poll</code> pending futures that it still has an interest in.</p>
<p>The <code>poll</code> function is not called repeatedly in a tight loop – instead,
it should only be called when the future indicates that it is ready to
make progress (by calling <code>wake()</code>). If you’re familiar with the
<code>poll(2)</code> or <code>select(2)</code> syscalls on Unix it’s worth noting that futures
typically do <em>not</em> suffer the same problems of “all wakeups must poll
all events”; they are more like <code>epoll(4)</code>.</p>
<p>An implementation of <code>poll</code> should strive to return quickly, and should
not block. Returning quickly prevents unnecessarily clogging up
threads or event loops. If it is known ahead of time that a call to
<code>poll</code> may end up taking awhile, the work should be offloaded to a
thread pool (or something similar) to ensure that <code>poll</code> can return
quickly.</p>
<h5 id="panics"><a href="#panics">Panics</a></h5>
<p>Once a future has completed (returned <code>Ready</code> from <code>poll</code>), calling its
<code>poll</code> method again may panic, block forever, or cause other kinds of
problems; the <code>Future</code> trait places no requirements on the effects of
such a call. However, as the <code>poll</code> method is not marked <code>unsafe</code>,
Rust’s usual rules apply: calls must never cause undefined behavior
(memory corruption, incorrect use of <code>unsafe</code> functions, or the like),
regardless of the future’s state.</p>
