<p>Leap seconds can theoretically follow <em>any</em> whole second.
The following would be a proper leap second at the time zone offset of UTC-00:03:57
(there are several historical examples comparable to this &quot;non-sense&quot; offset),
and therefore is allowed.</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>)
