    Description copied from interface: UniSubscription
    
    Requests the Uni to cancel and clean up resources. If the item is retrieved after cancellation, it is not forwarded to the subscriber. If the cancellation happens after the delivery of the item, this call is ignored.
    Calling this method, emits the cancellation event upstream.
