Required Methods

fn change(&mut self, new_state: S) -> bool

Returns true if it changed state successfully; false otherwise.

fn can_change(&self, new_state: S) -> bool

Returns true if it is possible to change state to new_state; false otherwise.

fn is_finish_state(state: S) -> bool

Returns true if it is a one of finish states.

fn at_finish_state(&self) -> bool

Returns true if the FSM is in a finish state.

fn finish_states() -> usize

Returns a number of total finish states.
