Struct aho_corasick::FullAcAutomaton
[−]
[src]
pub struct FullAcAutomaton<P> {
// some fields omitted
}A complete Aho-Corasick automaton.
This uses a single transition matrix that permits each input character to move to the next state with a single lookup in the matrix.
This is as fast as it gets, but it is guaranteed to use a lot of memory.
Namely, it will use at least 4 * 256 * #states, where the number of
states is capped at length of all patterns concatenated.
Methods
impl<P: AsRef<[u8]>> FullAcAutomaton<P>[src]
fn new<T: Transitions>(ac: AcAutomaton<P, T>) -> FullAcAutomaton<P>
Build a new expanded Aho-Corasick automaton from an existing Aho-Corasick automaton.
