[−][src]Struct show_notes::e031::unions::Either

pub struct Either<L: Copy, R: Copy> {
    pub tag: Tag,
    pub value: EitherValue<L, R>,
}

Uses an enum and a union to get close to a regular Rust enum.

Roughly, because the compiler won't check you for exhaustiveness, or even make sure you're using the tag and value pair the way you should!

Fields

tag: Tagvalue: EitherValue<L, R>
