Struct aho_corasick::AcAutomaton

pub struct AcAutomaton<P, T = Dense> {
    // some fields omitted
}

An Aho-Corasick finite automaton.

The type parameter P is the type of the pattern that was used to construct this AcAutomaton.

Methods

impl<P: AsRef<[u8]>> AcAutomaton<P>

fn new<I>(pats: I) -> AcAutomaton<P, Dense> where I: IntoIterator<Item=P>

Create a new automaton from an iterator of patterns.

The patterns must be convertible to bytes (&[u8]) via the AsRef trait.

impl<P: AsRef<[u8]>, T: Transitions> AcAutomaton<P, T>

fn with_transitions<I>(pats: I) -> AcAutomaton<P, T> where I: IntoIterator<Item=P>

Create a new automaton from an iterator of patterns.

This constructor allows one to choose the transition representation.

The patterns must be convertible to bytes (&[u8]) via the AsRef trait.

fn into_full(self) -> FullAcAutomaton<P>

Build out the entire automaton into a single matrix.

This will make searching as fast as possible at the expense of using at least 4 * 256 * #states bytes of memory.
