Request: Single.onErrorResumeNext(Func1<? super Throwable, Single<? extends T>> resumeFunction)

[ghost]

To match Observable's.

public Single<V> onErrorResumeNext(Func1<? super Throwable, Single<? extends T>> resumeFunction);

We are also interested in this feature. Currently we are in the process of switching Observable to Single where it makes sense. Not having this feature is blocking us. Since we would use this internally and not expose the details to users, does anybody know a workaround for accessing the Throwable?

[rtedin]

Since we are just interested in mapping the emitted exception to something else, here is something that just occurred to me. It's ugly, but it seems that it works as a temporary workaround in our use case. It may be useful for others too, so here it is:

single.onErrorReturn(throwable -> {
    throw mapException(throwable);
});

Where mapException maps the Throwable to one of our exceptions.

Isn't this a dupe of #3440 ?

[rtedin]

Yes, you're right. It's a duplicate.
