Is there a good way to define a Future of nothing?

[serbrech]

Hi, this might be a noob question.

When doing an async computation, there are cases where we don't have a resolve value, but we might have an error. Future requires to define a resolve type, since there is no non-generic definition.

Is that an unusual case for Future usage? Is there another construct that I should use?

struct{} means nothing in golang. For example you can use map[T]struct{} as a set.

I agree, this is the best way to do it.
