<p>This searcher encapsulates the logic required for finding all successive
non-overlapping matches in a haystack. In theory, iteration would look
something like this:</p>
<ol>
<li>Setting the start position to <code>0</code>.</li>
<li>Execute a regex search. If no match, end iteration.</li>
<li>Report the match and set the start position to the end of the match.</li>
<li>Go back to (2).</li>
</ol>
<p>And if this were indeed the case, its likely that <code>Searcher</code> wouldnt
exist. Unfortunately, because a regex may match the empty string, the above
logic wont work for all possible regexes. Namely, if an empty match is
found, then step (3) would set the start position of the search to the
position it was at. Thus, iteration would never end.</p>
<p>Instead, a <code>Searcher</code> knows how to detect these cases and forcefully
advance iteration in the case of an empty match that overlaps with a
previous match.</p>
<p>If you know that your regex cannot match any empty string, then the simple
algorithm described above will work correctly.</p>
<p>When possible, prefer the iterators defined on the regex engine youre
using. This tries to abstract over the regex engine and is thus a bit more
unwieldy to use.</p>
<p>In particular, a <code>Searcher</code> is not itself an iterator. Instead, it provides
<code>advance</code> routines that permit moving the search along explicitly. It also
provides various routines, like <a href="struct.Searcher.html#method.into_matches_iter" title="method regex_automata::util::iter::Searcher::into_matches_iter"><code>Searcher::into_matches_iter</code></a>, that
accept a closure (representing how a regex engine executes a search) and
returns a conventional iterator.</p>
<p>The lifetime parameters come from the <a href="../../struct.Input.html" title="struct regex_automata::Input"><code>Input</code></a> type passed to
<a href="struct.Searcher.html#method.new" title="associated function regex_automata::util::iter::Searcher::new"><code>Searcher::new</code></a>:</p>
<ul>
<li><code>'h</code> is the lifetime of the underlying haystack.</li>
</ul>
<h2 id="searcher-vs-iterator"><a href="#searcher-vs-iterator">Searcher vs Iterator</a></h2>
<p>Why does a search type with “advance” APIs exist at all when we also have
iterators? Unfortunately, the reasoning behind this split is a complex
combination of the following things:</p>
<ol>
<li>While many of the regex engines expose their own iterators, it is also
nice to expose this lower level iteration helper because it permits callers
to provide their own <code>Input</code> configuration. Moreover, a <code>Searcher</code> can work
with <em>any</em> regex engine instead of only the ones defined in this crate.
This way, everyone benefits from a shared iteration implementation.</li>
<li>There are many different regex engines that, while they have the same
match semantics, they have slightly different APIs. Iteration is just
complex enough to want to share code, and so we need a way of abstracting
over those different regex engines. While we could define a new trait that
describes any regex engine search API, it would wind up looking very close
to a closure. While there may still be reasons for the more generic trait
to exist, for now and for the purposes of iteration, we use a closure.
Closures also provide a lot of easy flexibility at the call site, in that
they permit the caller to borrow any kind of state they want for use during
each search call.</li>
<li>As a result of using closures, and because closures are anonymous types
that cannot be named, it is difficult to encapsulate them without both
costs to speed and added complexity to the public API. For example, in
defining an iterator type like
<a href="crate::dfa::regex::FindMatches"><code>dfa::regex::FindMatches</code></a>,
if we use a closure internally, its not possible to name this type in the
return type of the iterator constructor. Thus, the only way around it is
to erase the type by boxing it and turning it into a <code>Box&lt;dyn FnMut ...&gt;</code>.
This boxed closure is unlikely to be inlined <em>and</em> it infects the public
API in subtle ways. Namely, unless you declare the closure as implementing
<code>Send</code> and <code>Sync</code>, then the resulting iterator type wont implement it
either. But there are practical issues with requiring the closure to
implement <code>Send</code> and <code>Sync</code> that result in other API complexities that
are beyond the scope of this already long exposition.</li>
<li>Some regex engines expose more complex match information than just
“which pattern matched” and “at what offsets.” For example, the PikeVM
exposes match spans for each capturing group that participated in the
match. In such cases, it can be quite beneficial to reuse the capturing
group allocation on subsequent searches. A proper iterator doesnt permit
this API due to its interface, so its useful to have something a bit lower
level that permits callers to amortize allocations while also reusing a
shared implementation of iteration. (See the documentation for
<a href="struct.Searcher.html#method.advance" title="method regex_automata::util::iter::Searcher::advance"><code>Searcher::advance</code></a> for an example of using the “advance” API with the
PikeVM.)</li>
</ol>
<p>What this boils down to is that there are “advance” APIs which require
handing a closure to it for every call, and there are also APIs to create
iterators from a closure. The former are useful for <em>implementing</em>
iterators or when you need more flexibility, while the latter are useful
for conveniently writing custom iterators on-the-fly.</p>
<h2 id="example-iterating-with-captures"><a href="#example-iterating-with-captures">Example: iterating with captures</a></h2>
<p>Several regex engines in this crate over convenient iterator APIs over
<a href="../captures/struct.Captures.html" title="struct regex_automata::util::captures::Captures"><code>Captures</code></a> values. To do so, this requires allocating a new <code>Captures</code>
value for each iteration step. This can perhaps be more costly than you
might want. Instead of implementing your own iterator to avoid that
cost (which can be a little subtle if you want to handle empty matches
correctly), you can use this <code>Searcher</code> to do it for you:</p>

<p>Unlike the other iterator constructors, this accepts an initial

the iterator implementation clones it before returning it. The caller
must provide this value because the iterator is purposely ignorant
of the underlying regex engine and thus doesnt know how to create
one itself. More to the point, a <code>Captures</code> value itself has a few
different constructors, which change which kind of information is
available to query in exchange for search performance.</p>
