|
||
<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, it’s likely that <code>Searcher</code> wouldn’t
|
||
exist. Unfortunately, because a regex may match the empty string, the above
|
||
logic won’t 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 you’re
|
||
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, it’s 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<dyn FnMut ...></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 won’t 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 doesn’t permit
|
||
this API due to its interface, so it’s 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>
