Description
From #32836 (comment):
Under what conditions can you implement
Copy
for aunion
? For example, what if some variants are of non-Copy
type? All variants?
@RalfJung notes in #55149 (comment) that:
The RFC doesn't say anything about that, but I think indeed the answer should be "all variants".
