Struct tantivy_fst::automaton::Complement

pub struct Complement<A>(_);

An automaton that matches exactly when the automaton it wraps does not.

Trait Implementations

impl<A: Automaton> Automaton for Complement<A>

type State = ComplementState<A>

The type of the state used in the automaton.

fn start(&self) -> ComplementState<A>

Returns a single start state for this automaton.

fn is_match(&self, state: &ComplementState<A>) -> bool

Returns true if and only if state is a match state.

fn can_match(&self, state: &ComplementState<A>) -> bool

Returns true if and only if state can lead to a match in zero or more steps.

fn will_always_match(&self, state: &ComplementState<A>) -> bool

Returns true if and only if state matches and must match no matter what steps are taken.

fn accept(&self, state: &ComplementState<A>, byte: u8) -> ComplementState<A>

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.

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.

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.

fn complement(self) -> Complement<Self> where
    Self: Sized, 

Returns an automaton that matches the strings not matched by this automaton.

impl<A: Clone> Clone for Complement<A>

fn clone(&self) -> Complement<A>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<A: Debug> Debug for Complement<A>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
