the stream <code>a</code> provided.</p>
<p>The returned future will not return until all the data has been written, and
the future will resolve to the stream as well as the buffer (for reuse if
needed).</p>
<p>Any error which happens during writing will cause both the stream and the
buffer to get destroyed.</p>
<p>The <code>buf</code> parameter here only requires the <code>AsRef&lt;[u8]&gt;</code> trait, which should
be broadly applicable to accepting data which can be converted to a slice.
The <code>Window</code> struct is also available in this crate to provide a different
window into a slice if necessary.</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>)
