Is there a way to use existing structs as enum variants?

Question

I\'m using an enum for polymorphism, similar to the following:

enum MyType {
    Variant1 { a: i32, b: i32 },
    Variant2 { a: bool, b: bool },
}
         


        

Answer 1

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.
