pub enum Variants { Single { index: VariantIdx, }, Multiple { tag: Scalar, tag_encoding: TagEncoding, tag_field: usize, variants: IndexVec<VariantIdx, Layout>, }, }
Variants
Single enum variants, structs/tuples, unions, and all non-ADTs.

Fields of Single
index: VariantIdx
Enum-likes with more than one inhabited variant: each variant comes with a discriminant (usually the same as the variant index but the user can assign explicit discriminant values). That discriminant is encoded as a tag on the machine. The layout of each variant is a struct, and they all have space reserved for the tag. For enums, the tag is the sole field of the layout.
