Add ability to override type generated in gen.SliceOf(...) #41

Closed prateek closed 6 years ago

prateek commented 6 years ago

I have a situation where I need to override the type of the slice generated when using gen.SliceOf:

I have a base interface A which different structs (X & Y) implement
I have a generator for each of the structs, genX and genY

I'd like to use to gen.SliceOf(gen.OneOf(genX(), genY())) to generate a []A, to do so I have to provide an override for the type to SliceOf. This PR adds this functionality.

I don't have a good idea how to solve this problem any better way.
