Implementations

impl<N: Fsm> FsmState<N>[−]

pub fn new(data: Box<N>, state_cnt: Arc<AtomicUsize>) -> FsmState<N>

pub fn take_fsm(&self) -> Option<Box<N>>[−]

Take the fsm if it’s IDLE.

pub fn notify<S: FsmScheduler<Fsm = N>>(
    &self,
    scheduler: &S,
    mailbox: Cow<'_, BasicMailbox<N>>
)[−]

Notify fsm via a FsmScheduler.

pub fn release(&self, fsm: Box<N>)[−]
