Struct ralf::StateMachine

pub struct StateMachine<'a, T> where
    T: 'a + Copy + Clone,  { /* fields omitted */ }

State machine with a state of type T

Methods

impl<'a, T> StateMachine<'a, T> where
    T: 'a + Copy + Clone, 

pub fn new(initial_state: T) -> StateMachine<'a, T>

Create a new state machine from an initial state Note: The returned machine will be empty, so actions won't have any effects until reducers are added.

pub fn push_reducer(&mut self, reducer: &'a Reducer<T>) -> &mut Self

Add a reducer to the state machine

pub fn process(&self, a: &Action) -> &Self

Action processing logic, generate the new state from (prev_state, action) and set the internal state to the new state.

pub fn get_state(&self) -> T

Recover a copy of the state

Warning

This method will clone the entire state, and is therefore potentially expensive
