Struct fst::automaton::AlwaysMatch
[−]
[src]
pub struct AlwaysMatch;
An automaton that always matches.
This is useful in a generic context as a way to express that no automaton should be used.

impl Automaton for AlwaysMatch
[src]
type State = ()
The type of the state used in the automaton.
fn start(&self)
Returns a single start state for this automaton. Read more
fn is_match(&self, _: &()) -> bool
Returns true if and only if state
is a match state.
fn can_match(&self, _: &()) -> bool
Returns true if and only if state
can lead to a match in zero or more steps. Read more
fn will_always_match(&self, _: &()) -> bool
Returns true if and only if state
matches and must match no matter what steps are taken. Read more
fn accept(&self, _: &(), _: u8)
Return the next state given state
and an input.
fn starts_with(self) -> StartsWith<Self> where Self: Sized
Returns an automaton that matches the strings that start with something this automaton matches. Read more
fn union<Rhs: Automaton>(self, rhs: Rhs) -> Union<Self, Rhs> where Self: Sized
Returns an automaton that matches the strings matched by either this or the other automaton. Read more
fn intersection<Rhs: Automaton>(self, rhs: Rhs) -> Intersection<Self, Rhs> where Self: Sized
Returns an automaton that matches the strings matched by both this and the other automaton. Read more
