Struct StateMachineBuilder 

pub struct StateMachineBuilder<Event, State, Store> { /* private fields */ }

StateMachineBuilder is used to build a StateMachine.

Example

use fluent_state_machine::StateMachineBuilder;
 
let mut turnstyle = StateMachineBuilder::new((), "Locked")
    .state("Locked")
        .on("Coin").go_to("Unlocked")
    .state("Unlocked")
        .on("Push").go_to("Locked")
    .build().unwrap();

turnstyle.trigger("Coin");
assert_eq!(turnstyle.state, "Unlocked");

turnstyle.trigger("Push");
assert_eq!(turnstyle.state, "Locked");
