Methods

impl<T: Token, S> Expression<T, S>

fn token(input: T) -> Expression<T, S>

Returns an automaton that accepts the given token

fn sequence<I: Iterator<Item=T>>(tokens: I) -> Expression<T, S>

fn concat(self, other: Expression<T, S>) -> Expression<T, S>

Concatenate two automata

fn union(self, other: Expression<T, S>) -> Expression<T, S>

fn intersection(self, other: Expression<T, S>) -> Expression<T, S>

fn kleene(self) -> Expression<T, S>

fn optional(self) -> Expression<T, S>

fn on_enter<F: Fn(&mut S) + 'static>(self, action: F) -> Expression<T, S>

Specify an action to be invoked when evaluation enters the machine

fn on_exit<F: Fn(&mut S) + 'static>(self, action: F) -> Expression<T, S>
