<p>The identifier for a pattern corresponds to its relative position among
other patterns in a single finite state machine. Namely, when building
a multi-pattern regex engine, one must supply a sequence of patterns to
match. The position (starting at 0) of each pattern in that sequence
represents its identifier. This identifier is in turn used to identify and
report matches of that pattern in various APIs.</p>
<p>See the <ahref="struct.SmallIndex.html"title="struct regex_automata::util::primitives::SmallIndex"><code>SmallIndex</code></a> type for more information about what it means for
a pattern ID to be a “small index.”</p>
<p>Note that this type is defined in the
<ahref="index.html"title="mod regex_automata::util::primitives"><code>util::primitives</code></a> module, but it is also
re-exported at the crate root due to how common it is.</p>
