Struct BasicStateMachineBuilder

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

This builder enables us to assemble StateMachine (like crate::machine::BasicStateMachine) more easily.

Trait Implementations

impl<State, Input, Transition> Default for BasicStateMachineBuilder<State, Input, Transition>

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

fn default() -> Self

Returns the “default value” for a type.

impl<State, Input, Transition> StateMachineBuilder<State, Input, Transition> for BasicStateMachineBuilder<State, Input, Transition>

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

type Output = BasicStateMachine<State, Input, Transition>

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.
