Trait finny::FsmEventQueue

pub trait FsmEventQueue<F: FsmBackend> {
    pub fn enqueue<E: Into<<F as FsmBackend>::Events>>(
        &mut self, 
        event: E
    ) -> FsmResult<()>;
    pub fn dequeue(&mut self) -> Option<<F as FsmBackend>::Events>;
    pub fn len(&self) -> usize;
}

The event queueing trait for FSMs. Can be used from outside or from within the actions of the FSM.
