}An abstraction over automatons and their corresponding iterators.
The type parameter P is the type of the pattern that was used to
construct this Automaton.
Required Methods
fn next_state(&self, si: StateIdx, b: u8) -> StateIdx
Return the next state given the current state and next character.
fn has_match(&self, si: StateIdx, outi: usize) -> bool
Return true if and only if the given state and current pattern index indicate a match.
fn get_match(&self, si: StateIdx, outi: usize, texti: usize) -> Match
Build a match given the current state, pattern index and input index.
fn start_bytes(&self) -> &[u8]
Return the set of bytes that have transitions in the root state.
fn patterns(&self) -> &[P]
Returns all of the patterns matched by this automaton.
The order of the patterns is the order in which they were added.
fn pattern(&self, i: usize) -> &P
Returns the pattern indexed at i.
The index corresponds to the position at which the pattern was added
to the automaton, starting at 0.
Provided Methods
fn len(&self) -> usize
Return the number of patterns in the automaton.
fn is_empty(&self) -> bool
Returns true if the automaton has no patterns.
fn find<'a, 's, Q: ?Sized + AsRef<[u8]>>(
&'a self,
s: &'s Q
) -> Matches<'a, 's, P, Self> where
Self: Sized,
&'a self,
s: &'s Q
) -> Matches<'a, 's, P, Self> where
Self: Sized,
Returns an iterator of non-overlapping matches in s.
fn find_overlapping<'a, 's, Q: ?Sized + AsRef<[u8]>>(
&'a self,
s: &'s Q
) -> MatchesOverlapping<'a, 's, P, Self> where
Self: Sized,
&'a self,
s: &'s Q
) -> MatchesOverlapping<'a, 's, P, Self> where
Self: Sized,
Returns an iterator of overlapping matches in s.
fn stream_find<'a, R: Read>(&'a self, rdr: R) -> StreamMatches<'a, R, P, Self> where
Self: Sized,
Self: Sized,
Returns an iterator of non-overlapping matches in the given reader.
fn stream_find_overlapping<'a, R: Read>(
&'a self,
rdr: R
) -> StreamMatchesOverlapping<'a, R, P, Self> where
Self: Sized,
&'a self,
rdr: R
) -> StreamMatchesOverlapping<'a, R, P, Self> where
Self: Sized,
Returns an iterator of overlapping matches in the given reader.
