<p>The trait inherits from <a href="https://doc.rust-lang.org/1.59.0/std/io/trait.Write.html"><code>std::io::Write</code></a> and indicates that an I/O object is
<strong>nonblocking</strong>. All non-blocking I/O objects must return an error when
bytes cannot be written instead of blocking the current thread.</p>
<p>Specifically, this means that the <a href="trait.AsyncWrite.html#tymethod.poll_write"><code>poll_write</code></a> function will return one of
the following:</p>
<ul>
<li>
<p><code>Poll::Ready(Ok(n))</code> means that <code>n</code> bytes of data was immediately
written.</p>
</li>
<li>
<p><code>Poll::Pending</code> means that no data was written from the buffer
provided. The I/O object is not currently writable but may become writable
in the future. Most importantly, <strong>the current future’s task is scheduled
to get unparked when the object is writable</strong>. This means that like
<code>Future::poll</code> you’ll receive a notification when the I/O object is
writable again.</p>
</li>
<li>
<p><code>Poll::Ready(Err(e))</code> for other errors are standard I/O errors coming from the
underlying object.</p>
</li>
</ul>
<p>This trait importantly means that the <a href="https://doc.rust-lang.org/1.59.0/std/io/trait.Write.html#tymethod.write"><code>write</code></a> method only works in
the context of a future’s task. The object may panic if used outside of a task.</p>
<p>Note that this trait also represents that the <a href="https://doc.rust-lang.org/1.59.0/std/io/trait.Write.html#tymethod.flush"><code>Write::flush</code></a> method
works very similarly to the <code>write</code> method, notably that <code>Ok(())</code> means that the
writer has successfully been flushed, a “would block” error means that the
current task is ready to receive a notification when flushing can make more
progress, and otherwise normal errors can happen as well.</p>
<p>Utilities for working with <code>AsyncWrite</code> values are provided by
<a href="crate::io::AsyncWriteExt"><code>AsyncWriteExt</code></a>.</p>

the I/O connection has completely shut down.</p>
<p>This method is intended to be used for asynchronous shutdown of I/O
connections. For example this is suitable for implementing shutdown of a
TLS connection or calling <code>TcpStream::shutdown</code> on a proxied connection.
Protocols sometimes need to flush out final pieces of data or otherwise
perform a graceful shutdown handshake, reading/writing more data as
appropriate. This method is the hook for such protocols to implement the
graceful shutdown logic.</p>
<p>This <code>shutdown</code> method is required by implementers of the
<code>AsyncWrite</code> trait. Wrappers typically just want to proxy this call
through to the wrapped type, and base types will typically implement
shutdown logic here or just return <code>Ok(().into())</code>. Note that if you’re
wrapping an underlying <code>AsyncWrite</code> a call to <code>shutdown</code> implies that
transitively the entire stream has been shut down. After your wrapper’s
shutdown logic has been executed you should shut down the underlying
stream.</p>
<p>Invocation of a <code>shutdown</code> implies an invocation of <code>flush</code>. Once this
method returns <code>Ready</code> it implies that a flush successfully happened
before the shutdown happened. That is, callers don’t need to call
<code>flush</code> before calling <code>shutdown</code>. They can rely that by calling
<code>shutdown</code> any pending buffered data will be written out.</p>
<h5 id="return-value" class="section-header"><a href="#return-value">Return value</a></h5>
<p>This function returns a <code>Poll&lt;io::Result&lt;()&gt;&gt;</code> classified as such:</p>
<ul>
<li>
<p><code>Poll::Ready(Ok(()))</code> - indicates that the connection was
successfully shut down and is now safe to deallocate/drop/close
resources associated with it. This method means that the current task
will no longer receive any notifications due to this method and the
I/O object itself is likely no longer usable.</p>
</li>
<li>
<p><code>Poll::Pending</code> - indicates that shutdown is initiated but could
not complete just yet. This may mean that more I/O needs to happen to
continue this shutdown operation. The current task is scheduled to
receive a notification when it’s otherwise ready to continue the
shutdown operation. When woken up this method should be called again.</p>
</li>
<li>
<p><code>Poll::Ready(Err(e))</code> - indicates a fatal error has happened with shutdown,
indicating that the shutdown operation did not complete successfully.
This typically means that the I/O object is no longer usable.</p>
</li>
</ul>
<h5 id="errors" class="section-header"><a href="#errors">Errors</a></h5>
<p>This function can return normal I/O errors through <code>Err</code>, described
above. Additionally this method may also render the underlying
<code>Write::write</code> method no longer usable (e.g. will return errors in the
future). It’s recommended that once <code>shutdown</code> is called the
<code>write</code> method is no longer called.</p>
<h5 id="panics" class="section-header"><a href="#panics">Panics</a></h5>
<p>This function will panic if not called within the context of a future’s
task.</p>
