<p>The default is <a href="../../enum.MatchKind.html#variant.LeftmostFirst" title="variant regex_automata::MatchKind::LeftmostFirst"><code>MatchKind::LeftmostFirst</code></a>, which corresponds to the
|
||
match semantics of Perl-like regex engines. That is, when multiple
|
||
patterns would match at the same leftmost position, the pattern that
|
||
appears first in the concrete syntax is chosen.</p>
|
||
<p>Currently, the only other kind of match semantics supported is
|
||
<a href="../../enum.MatchKind.html#variant.All" title="variant regex_automata::MatchKind::All"><code>MatchKind::All</code></a>. This corresponds to “classical DFA” construction
|
||
where all possible matches are visited.</p>
|
||
<p>When it comes to the one-pass DFA, it is rarer for preference order and
|
||
“longest match” to actually disagree. Since if they did disagree, then
|
||
the regex typically isn’t one-pass. For example, searching <code>Samwise</code>
|
||
for <code>Sam|Samwise</code> will report <code>Sam</code> for leftmost-first matching and
|
||
<code>Samwise</code> for “longest match” or “all” matching. However, this regex is
|
||
not one-pass if taken literally. The equivalent regex, <code>Sam(?:|wise)</code>
|
||
is one-pass and <code>Sam|Samwise</code> may be optimized to it.</p>
|
||
<p>The other main difference is that “all” match semantics don’t support
|
||
non-greedy matches. “All” match semantics always try to match as much
|
||
as possible.</p>

|
||
<p>This option is enabled by default and should never be disabled unless
|
||
one is debugging a one-pass DFA.</p>
|
||
<p>When enabled, the DFA will use a map from all possible bytes to their
|
||
corresponding equivalence class. Each equivalence class represents a
|
||
set of bytes that does not discriminate between a match and a non-match
|
||
in the DFA. For example, the pattern <code>[ab]+</code> has at least two
|
||
equivalence classes: a set containing <code>a</code> and <code>b</code> and a set containing
|
||
every byte except for <code>a</code> and <code>b</code>. <code>a</code> and <code>b</code> are in the same
|
||
equivalence class because they never discriminate between a match and a
|
||
non-match.</p>
|
||
<p>The advantage of this map is that the size of the transition table
|
||
can be reduced drastically from (approximately) <code>#states * 256 * sizeof(StateID)</code> to <code>#states * k * sizeof(StateID)</code> where <code>k</code> is the
|
||
number of equivalence classes (rounded up to the nearest power of 2).
|
||
As a result, total space usage can decrease substantially. Moreover,
|
||
since a smaller alphabet is used, DFA compilation becomes faster as
|
||
well.</p>
|
||
<p><strong>WARNING:</strong> This is only useful for debugging DFAs. Disabling this
|
||
does not yield any speed advantages. Namely, even when this is
|
||
disabled, a byte class map is still used while searching. The only
|
||
difference is that every byte will be forced into its own distinct
|
||
equivalence class. This is useful for debugging the actual generated
|
||
transitions because it lets one see the transitions defined on actual
|
||
bytes instead of the equivalence classes.</p>
