Macro for defining deterministic state machines - non-serde version

This macro is used to quickly define deterministic state machines where each state+input combination can have at most one next state.

Syntax

use yasm::define_state_machine;
define_state_machine! {
    name: MyStateMachine,
    states: { State1, State2, State3 },
    inputs: { Input1, Input2 },
    initial: State1,
    transitions: {
        State1 + Input1 => State2,
        State2 + Input2 => State3,
    }
}

Parameters

• name: Name of the state machine struct
• states: List of all possible states
• inputs: List of all possible inputs
• initial: Initial state
• transitions: State transition rules in the format from_state + input => to_state
