Variants

Literal(MatchLiteralType)

A single or multiple literal search. This is only used when the regex can be decomposed into unambiguous literal search.

Dfa

A normal DFA search.

DfaAnchoredReverse

A reverse DFA search starting from the end of a haystack.

DfaSuffix

A reverse DFA search with suffix literal scanning.

DfaMany

Use the DFA on two or more regular expressions.

Nfa(MatchNfaType)

An NFA variant.

Nothing

No match is ever possible, so don't ever try to search.
