<p>Calling next on a fused iterator that has returned <code>None</code> once is guaranteed
to return <a href="../../std/option/enum.Option.html#variant.None"><code>None</code></a> again. This trait is should be implemented by all iterators
that behave this way because it allows for some significant optimizations.</p>
<p>Note: In general, you should not use <code>FusedIterator</code> in generic bounds if
you need a fused iterator. Instead, you should just call <a href="../../std/iter/trait.Iterator.html#method.fuse"><code>Iterator::fuse</code></a>
on the iterator. If the iterator is already fused, the additional <a href="../../std/iter/struct.Fuse.html"><code>Fuse</code></a>

<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>)
