InfallibleType

public protocol InfallibleType : ObservableConvertibleType

Infallible is an Observable-like push-style interface which is guaranteed to not emit error events.

Unlike SharedSequence, it does not share its resources or replay its events, but acts as a standard Observable.

                subscribe(with:onNext:onCompleted:onDisposed:)
                ` Extension method 

Subscribes an element handler, a completion handler and disposed handler to an observable sequence.

Error callback is not exposed because Infallible can’t error out.

Also, take in an object and provide an unretained, safe to use (i.e. not implicitly unwrapped), reference to it along with the events emitted by the sequence.

Note

If object can’t be retained, none of the other closures will be invoked.

Declaration

Swift

func subscribe<Object: AnyObject>(
    with object: Object,
    onNext: ((Object, Element) -> Void)? = nil,
    onCompleted: ((Object) -> Void)? = nil,
    onDisposed: ((Object) -> Void)? = nil
) -> Disposable

Parameters

| object |

The object to provide an unretained reference on.

| | onNext |

Action to invoke for each element in the observable sequence.

| | onCompleted |

Action to invoke upon graceful termination of the observable sequence. gracefully completed, errored, or if the generation is canceled by disposing subscription)

| | onDisposed |

Action to invoke upon any type of termination of sequence (if the sequence has gracefully completed, errored, or if the generation is canceled by disposing subscription)

|

Return Value

Subscription object used to unsubscribe from the observable sequence.
