<p>Basic examples of sinks include the sending side of:</p>
<ul>
<li>Channels</li>
<li>Sockets</li>
<li>Pipes</li>
</ul>
<p>In addition to such “primitive” sinks, it’s typical to layer additional
functionality, such as buffering, on top of an existing sink.</p>
<p>Sending to a sink is “asynchronous” in the sense that the value may not be
sent in its entirety immediately. Instead, values are sent in a two-phase
way: first by initiating a send, and then by polling for completion. This
two-phase setup is analogous to buffered writing in synchronous code, where
writes often succeed immediately, but internally are buffered and are
<em>actually</em> written only upon flushing.</p>
<p>In addition, the <code>Sink</code> may be <em>full</em>, in which case it is not even possible
to start the sending process.</p>
<p>As with <code>Future</code> and <code>Stream</code>, the <code>Sink</code> trait is built from a few core
required methods, and a host of default methods for working in a
higher-level way. The <code>Sink::send_all</code> combinator is of particular
importance: you can use it to send an entire stream to a sink, which is
the simplest way to ultimately consume a stream.</p>

<p>As the name suggests, this method only <em>begins</em> the process of sending
the item. If the sink employs buffering, the item isn’t fully processed
until the buffer is fully flushed. Since sinks are designed to work with
asynchronous I/O, the process of actually writing out the data to an
underlying object takes place asynchronously. <strong>You <em>must</em> use
<code>poll_flush</code> or <code>poll_close</code> in order to guarantee completion of a
send</strong>.</p>
<p>Implementations of <code>poll_ready</code> and <code>start_send</code> will usually involve
flushing behind the scenes in order to make room for new messages.
It is only necessary to call <code>poll_flush</code> if you need to guarantee that
<em>all</em> of the items placed into the <code>Sink</code> have been sent.</p>
