Is there a way to use existing structs as enum variants?
There have been multiple RFCs about making enum variants their own type:
- RFC 1450: Types for enum variants
- RFC 2593: Enum variant types
Unfortunately, they have been postponed or not yet decided on as this is not considered a language priority.
This means that right now, the way you have proposed is the only way to have types for enum variants.
No, that's exactly how that works.
