    where
        I: Inspect,

Check if this transition is allowed to be entered.

Required methods

fn guard<'a, Q: FsmEventQueue<F>>(
    event: &E,
    context: &EventContext<'a, F, Q>,
    states: &'a <F as FsmBackend>::States
) -> bool

Return a boolean value whether this transition is usable at the moment. The check shouln’t mutate any structures.

Provided methods

fn execute_guard<'a, 'b, 'c, 'd, Q: FsmEventQueue<F>, I, T>(
    context: &'d mut DispatchContext<'a, 'b, 'c, F, Q, I, T>,
    event: &E,
    region: FsmRegionId,
    inspect_event_ctx: &mut I
) -> bool where
    I: Inspect,
    Self: Sized,
    T: FsmTimers<F>,
