- <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>)
