[2.x] Maybe.switchIfEmpty(CompletableSource)

[kevmo314]

In the same vein as #4544, can we get Maybe.switchIfEmpty(CompletableSource)? It would be identical to maybe.switchIfEmpty(completable.toMaybe()).

Is there a reason the manual application of toMaybe() is a problem for you? We usually don't add trivial or many conveninence operators.

[kevmo314]

We have a CompletableSubject which doesn't have toMaybe(). But I guess more broadly, CompletableSource is looser and doesn't actually require toMaybe() to exist and it seems consistent with the other overloads of Maybe.switchIfEmpty().

[akarnokd]

CompletableSubject extends Completable thus it has toMaybe, not sure why you have problems (maybe forgot to add the target type argument for the conversion?)

switchIfEmpty(Single) makes sense on its own as it return a Single expecting and implying there is going to be a success item or an error. Switching to a Completable doesn't change the return type and thus .toMaybe conversion won't introduce more conversions down the line like switchIfEmpty(Single.toMaybe()) would.

Ah okay we figured out what was going on on our end. Thanks for the context behind SingleSource, that makes sense. I'll close this one out as .toMaybe() isn't a problem. :)
