<p>A <code>Seq</code> is very much like a set in that it represents a union of its
members. That is, it corresponds to a set of literals where at least one
must match in order for a particular <ahref="../struct.Hir.html"title="struct regex_syntax::hir::Hir"><code>Hir</code></a> expression to match. (Whether
this corresponds to the entire <code>Hir</code> expression, a prefix of it or a suffix
of it depends on how the <code>Seq</code> was extracted from the <code>Hir</code>.)</p>
<p>It is also unlike a set in that multiple identical literals may appear,
and that the order of the literals in the <code>Seq</code> matters. For example, if
the sequence is <code>[sam, samwise]</code> and leftmost-first matching is used, then
<code>samwise</code> can never match and the sequence is equivalent to <code>[sam]</code>.</p>
<p>A <code>Seq</code> has a few different logical states to consider:</p>
<ul>
<li>The sequence can represent “any” literal. When this happens, the set does
not have a finite size. The purpose of this state is to inhibit callers
from making assumptions about what literals are required in order to match
a particular <ahref="../struct.Hir.html"title="struct regex_syntax::hir::Hir"><code>Hir</code></a> expression. Generally speaking, when a set is in this
state, literal optimizations are inhibited. A good example of a regex that
will cause this sort of set to appear is <code>[A-Za-z]</code>. The character class
is just too big (and also too narrow) to be usefully expanded into 52
different literals. (Note that the decision for when a seq should become
infinite is determined by the caller. A seq itself has no hard-coded
limits.)</li>
<li>The sequence can be empty, in which case, it is an affirmative statement
that there are no literals that can match the corresponding <code>Hir</code>.
Consequently, the <code>Hir</code> never matches any input. For example, <code>[a&&b]</code>.</li>
<li>The sequence can be non-empty, in which case, at least one of the
literals must match in order for the corresponding <code>Hir</code> to match.</li>
<p>An empty sequence matches zero literals, and thus corresponds to a
regex that itself can never match.</p>

any literal.</p>
<p>A sequence without finite size does not reveal anything about the
characteristics of the literals in its set. There are no fixed prefixes
or suffixes, nor are lower or upper bounds on the length of the literals
in the set known.</p>
<p>This is useful to represent constructs in a regex that are “too big”
to useful represent as a sequence of literals. For example, <code>[A-Za-z]</code>.
When sequences get too big, they lose their discriminating nature and
are more likely to produce false positives, which in turn makes them
less likely to speed up searches.</p>
<p>More pragmatically, for many regexes, enumerating all possible literals
is itself not possible or might otherwise use too many resources. So
constraining the size of sets during extraction is a practical trade
off to make.</p>

respecting the preference order of its literals.</p>
<p>The specific way “optimization” works is meant to be an implementation
detail, as it essentially represents a set of heuristics. The goal
that optimization tries to accomplish is to make the literals in this
set reflect inputs that will result in a more effective prefilter.
Principally by reducing the false positive rate of candidates found by
the literals in this sequence. That is, when a match of a literal is
found, we would like it to be a strong predictor of the overall match
of the regex. If it isn’t, then much time will be spent starting and
stopping the prefilter search and attempting to confirm the match only
to have it fail.</p>
<p>Some of those heuristics might be:</p>
<ul>
<li>Identifying a common prefix from a larger sequence of literals, and
shrinking the sequence down to that single common prefix.</li>
<li>Rejecting the sequence entirely if it is believed to result in very
high false positive rate. When this happens, the sequence is made
infinite.</li>
<li>Shrinking the sequence to a smaller number of literals representing
prefixes, but not shrinking it so much as to make literals too short.
(A sequence with very short literals, of 1 or 2 bytes, will typically
result in a higher false positive rate.)</li>
</ul>
<p>Optimization should only be run once extraction is complete. Namely,
optimization may make assumptions that do not compose with other
operations in the middle of extraction. For example, optimization will
reduce <code>[E(sam), E(samwise)]</code> to <code>[E(sam)]</code>, but such a transformation
is only valid if no other extraction will occur. If other extraction
may occur, then the correct transformation would be to <code>[I(sam)]</code>.</p>
