|

<p>The purpose of this type is to permit callers to construct a substring
|
||
searcher that can be used to search haystacks without the overhead of
|
||
constructing the searcher in the first place. This is a somewhat niche
|
||
concern when it’s necessary to re-use the same needle to search multiple
|
||
different haystacks with as little overhead as possible. In general, using
|
||
<a href="fn.find.html" title="find"><code>find</code></a> is good enough, but <code>Finder</code> is useful when you can meaningfully
|
||
observe searcher construction time in a profile.</p>
|
||
<p>When the <code>std</code> feature is enabled, then this type has an <code>into_owned</code>
|
||
version which permits building a <code>Finder</code> that is not connected to
|
||
the lifetime of its needle.</p>
