Macro sfsm_proc::add_state_machine

add_state_machine!() { /* proc-macro */ }

Generates a state machine from a given state machine definition.

The state machine definition is expected too hold to the following pattern:

add_state_machine!(
    StateMachineName,
    InitialState,
    [State1, State2, StateN, ...],
    [StateN => StateN, ...]
);

• StateMachineName: Defines the name of the state machine.
• InitialState: The initial state the state machine will start with.
• [State1, State2, StateN, …]: Specifies all state structs that will be known to the state machine. Each state must implement the State trait.
• [StateN => StateN, …]: Defines all transitions between states that can occur. For each transition, the state must implement the according Transition trait.

An example might look like this:

add_state_machine!(
        #[derive(Debug)]
        Rocket,
        Action<Ascent>,
        [Action<Ascent>, Action<Descent>],
        [
            Action<Ascent> => Action<Descent>,
            Action<Descent> => Action<Ascent>
        ]
);
