<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>)
|
|
|
|
|
|
