Struct BasicStateMachine 

pub struct BasicStateMachine<State, Input, Transition>
where
    Transition: Fn(&State, Input) -> State,
    State: Clone,
{ /* private fields */ }

The basic state machine implementation. It holds initial_state, current_state, transition function.

Trait Implementations

impl<State, Input, Transition> StateMachine<State, Input> for BasicStateMachine<State, Input, Transition>

where Transition: Fn(&State, Input) -> State, State: Clone,

fn current_state(&self) -> State

Returns the current state of the state machine.

fn consume(&self, input: Input) -> State

Returns the result of state transition according to input and the definition of transition function.

fn peek(&self, input: Input) -> State

Returns the next state from the current state but the state machine retains in its current state.

fn reset(&self) -> State

Resets the current state to the initial state.

fn set(&self, new_state: State)

Set a new state forcibly to the current state.
