<pre class='rust struct'>pub struct PollEvented&lt;E&gt; { /* fields omitted */ }</pre><div class='docblock'><p>A concrete implementation of a stream of readiness notifications for I/O
objects that originates from an event loop.</p>
<p>Created by the <code>PollEvented::new</code> method, each <code>PollEvented</code> is
associated with a specific event loop and source of events that will be
registered with an event loop.</p>
<p>An instance of <code>PollEvented</code> is essentially the bridge between the <code>mio</code>
world and the <code>tokio-core</code> world, providing abstractions to receive
notifications about changes to an object's <code>mio::Ready</code> state.</p>
<p>Each readiness stream has a number of methods to test whether the underlying
object is readable or writable. Once the methods return that an object is
readable/writable, then it will continue to do so until the <code>need_read</code> or
<code>need_write</code> methods are called.</p>
<p>That is, this object is typically wrapped in another form of I/O object.
It's the responsibility of the wrapper to inform the readiness stream when a
&quot;would block&quot; I/O event is seen. The readiness stream will then take care of
any scheduling necessary to get notified when the event is ready again.</p>
<p>You can find more information about creating a custom I/O object <a href="https://tokio.rs/docs/going-deeper-tokio/core-low-level/#custom-io">online</a>.</p>
<h2 id="readiness-to-readwrite" class="section-header"><a href="#readiness-to-readwrite">Readiness to read/write</a></h2>
<p>A <code>PollEvented</code> allows listening and waiting for an arbitrary <code>mio::Ready</code>
instance, including the platform-specific contents of <code>mio::Ready</code>. At most
two future tasks, however, can be waiting on a <code>PollEvented</code>. The
<code>need_read</code> and <code>need_write</code> methods can block two separate tasks, one on
reading and one on writing. Not all I/O events correspond to read/write,
however!</p>
<p>To account for this a <code>PollEvented</code> gets a little interesting when working
with an arbitrary instance of <code>mio::Ready</code> that may not map precisely to
&quot;write&quot; and &quot;read&quot; tasks. Currently it is defined that instances of
<code>mio::Ready</code> that do <em>not</em> return true from <code>is_writable</code> are all notified
through <code>need_read</code>, or the read task.</p>
<p>In other words, <code>poll_ready</code> with the <code>mio::UnixReady::hup</code> event will block
the read task of this <code>PollEvented</code> if the <code>hup</code> event isn't available.
Essentially a good rule of thumb is that if you're using the <code>poll_ready</code>
method you want to also use <code>need_read</code> to signal blocking and you should
otherwise probably avoid using two tasks on the same <code>PollEvented</code>.</p>

<h2>Search Tricks</h2>
<p>
Prefix searches with a type followed by a colon (e.g.
<code>fn:</code>) to restrict the search to a given type.
</p>
<p>
Accepted types are: <code>fn</code>, <code>mod</code>,
<code>struct</code>, <code>enum</code>,
<code>trait</code>, <code>type</code>, <code>macro</code>,
and <code>const</code>.
</p>
<p>
Search functions by type signature (e.g.
<code>vec -> usize</code> or <code>* -> vec</code>)
