Enum IrqRegisterResult 

pub enum IrqRegisterResult<'cell> {
    Registered(IrqWaitToken<'cell>),
    ConsumedPending,
    NotificationInFlight(IrqWaitToken<'cell>),
    Occupied,
}

Outcome of task-context waiter registration.

Variants

Registered(IrqWaitToken<'cell>)

The cell owns the sole waiter until notify or unregister.

ConsumedPending

An earlier or concurrent interrupt consumed the registration.

An earlier pending event is returned synchronously without waking the currently running task. The registration is detached on return.

NotificationInFlight(IrqWaitToken<'cell>)

A concurrent notifier owns the registration and will release and wake it.

The task may abort its park once the token is detached, but it must quiesce the token before reusing the registration or wake payload.

Occupied

Another waiter is registered, or this registration is still in use.
