Struct aho_corasick::FindIter

pub struct FindIter<'a, 'b, S: StateID> { /* private fields */ }

An iterator of non-overlapping matches in a particular haystack.

This iterator yields matches according to the MatchKind used by this automaton.

This iterator is constructed via the AhoCorasick::find_iter method.

The type variable S refers to the representation used for state identifiers. (By default, this is usize.)

The lifetime 'a refers to the lifetime of the AhoCorasick automaton.

The lifetime 'b refers to the lifetime of the haystack being searched.
