Variants

Empty

No literals. (Never advances through the input.)

Bytes(SingleByteSet)

A set of four or more single byte literals.

FreqyPacked(FreqyPacked)

A single substring, find using memchr and frequency analysis.

BoyerMoore(BoyerMooreSearch)

A single substring, find using Boyer-Moore.

AC(FullAcAutomaton<Literal>)

An Aho-Corasick automaton.

TeddySSSE3(TeddySSSE3)

A simd accelerated multiple string matcher. Used only for a small number of small literals.

TeddyAVX2(TeddyAVX2)

A simd accelerated multiple string matcher. Used only for a small number of small literals. This uses 256-bit vectors.
