Trait StateMachineBuilder 

pub trait StateMachineBuilder<State, Input, Transition>
where
    Transition: Fn(&State, Input) -> State,
    State: Clone,
{
    type Output;

    // Required methods
    fn start() -> Self;
    fn initial_state(self, state: State) -> Self;
    fn current_state(self, state: State) -> Self;
    fn transition(self, next: Transition) -> Self;
    fn build(self) -> Result<Self::Output, Box<dyn Error>>;
}

Required Associated Types

type Output

Required Methods

fn start() -> Self

Starts the builder.

fn initial_state(self, state: State) -> Self

Sets particular initial state to the state machine.

fn current_state(self, state: State) -> Self

Sets particular state to the current state.

fn transition(self, next: Transition) -> Self

Sets particular transition algorithm to the state machine.

fn build(self) -> Result<Self::Output, Box<dyn Error>>

To finish the builder. If it fails, returns crate::machine::error::StateMachineError.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
