<h1>Search tricks</h1>
<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>typedef</code> (or
<code>tdef</code>).
</p>
<p>
Search functions by type signature (e.g.
<code>vec -> usize</code>)
