<p>The iteration represents an alternation of comprehensive byte sequences
that match precisely the set of UTF-8 encoded scalar values.</p>
<p>A byte sequence corresponds to one of the scalar values in the range given
if and only if it completely matches exactly one of the sequences of byte
ranges produced by this iterator.</p>
<p>Each sequence of byte ranges matches a unique set of bytes. That is, no two
sequences will match the same bytes.</p>

<p>If this example seems circuitous, that&#39;s because it is! It&#39;s meant to be
illustrative. In practice, you could just try to decode your byte sequence
and compare it with the scalar value range directly. However, this is not
always possible (for example, in a byte based automaton).</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>)
