How to map a completed event to an interrupt event when take(duringLifetimeOf:) happened in ReactiveSwift

Question

For example, I want to send a request in my viewModel, if the viewModel is dealloc. The request signal should send interrupt event.

This is my code

func request() -> SignalProducer<Data, Error> {
    let request: SignalProducer<Data, Error> = ..... (This signal is from another module)
    return request.take(duringLifetimeOf: self)
}

This code will send a completed event instead of an interrupt event when self is dealloc. Because take(duringLifetimeOf:) API said:

Forward events from self until object deinitializes, at which point the returned producer will complete.

If I am the caller of this request(). I want to know whether my request is done. If the request is canceled due to the "self" being dealloc . Then I will get a completed event. This is not reasonable.

Is my thought right about mapping the completed event to the interrupt event?

What to do if my thought is right?
