Enum rustc_middle::ty::VariantDiscr

pub enum VariantDiscr {
    Explicit(DefId),
    Relative(u32),
}

Variants

Explicit(DefId)

Explicit value for this variant, i.e., X = 123. The DefId corresponds to the embedded constant.

Relative(u32)

The previous variant’s discriminant plus one. For efficiency reasons, the distance from the last Explicit discriminant is being stored, or 0 for the first variant, if it has none.
