|
|||
|
|
<p>This builder permits configuring options for the syntax of a pattern, the
|
|||
|
|
NFA construction, the lazy DFA construction and finally the regex searching
|
|||
|
|
itself. This builder is different from a general purpose regex builder
|
|||
|
|
in that it permits fine grain configuration of the construction process.
|
|||
|
|
The trade off for this is complexity, and the possibility of setting a
|
|||
|
|
configuration that might not make sense. For example, there are two
|
|||
|
|
different UTF-8 modes:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li><a href="../../util/syntax/struct.Config.html#method.utf8" title="method regex_automata::util::syntax::Config::utf8"><code>syntax::Config::utf8</code></a> controls
|
|||
|
|
whether the pattern itself can contain sub-expressions that match invalid
|
|||
|
|
UTF-8.</li>
|
|||
|
|
<li><a href="../../nfa/thompson/struct.Config.html#method.utf8" title="method regex_automata::nfa::thompson::Config::utf8"><code>thompson::Config::utf8</code></a> controls how the regex iterators themselves
|
|||
|
|
advance the starting position of the next search when a match with zero
|
|||
|
|
length is found.</li>
|
|||
|
|
</ul>
|
|||
|
|
<p>Generally speaking, callers will want to either enable all of these or
|
|||
|
|
disable all of these.</p>
|
|||
|
|
<p>Internally, building a regex requires building two hybrid NFA/DFAs,
|
|||
|
|
where one is responsible for finding the end of a match and the other is
|
|||
|
|
responsible for finding the start of a match. If you only need to detect
|
|||
|
|
whether something matched, or only the end of a match, then you should use
|
|||
|
|
a <a href="../dfa/struct.Builder.html" title="struct regex_automata::hybrid::dfa::Builder"><code>dfa::Builder</code></a> to construct a single hybrid NFA/DFA, which is cheaper
|
|||
|
|
than building two of them.</p>
|
|||
|
|
<h2 id="example"><a href="#example">Example</a></h2>
|
|||
|
|
<p>This example shows how to disable UTF-8 mode in the syntax and the regex
|
|||
|
|
itself. This is generally what you want for matching on arbitrary bytes.</p>

|
|||
|
|
<p>This is useful when you’ve built a forward and reverse lazy DFA
|
|||
|
|
separately, and want to combine them into a single regex. Once build,
|
|||
|
|
the individual DFAs given can still be accessed via <a href="struct.Regex.html#method.forward" title="method regex_automata::hybrid::regex::Regex::forward"><code>Regex::forward</code></a>
|
|||
|
|
and <a href="struct.Regex.html#method.reverse" title="method regex_automata::hybrid::regex::Regex::reverse"><code>Regex::reverse</code></a>.</p>
|
|||
|
|
<p>It is important that the reverse lazy DFA be compiled under the
|
|||
|
|
following conditions:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li>It should use <a href="../../enum.MatchKind.html#variant.All" title="variant regex_automata::MatchKind::All"><code>MatchKind::All</code></a> semantics.</li>
|
|||
|
|
<li>It should match in reverse.</li>
|
|||
|
|
<li>Otherwise, its configuration should match the forward DFA.</li>
|
|||
|
|
</ul>
|
|||
|
|
<p>If these conditions aren’t satisfied, then the behavior of searches is
|
|||
|
|
unspecified.</p>
|
|||
|
|
<p>Note that when using this constructor, no configuration is applied.
|
|||

Since this routine provides the DFAs to the builder, there is no

|
|
opportunity to apply other configuration options.</p>
