Expand description
Compiler-internal trait used to indicate the type of enum discriminants.
This trait is automatically implemented for every type and does not add any
guarantees to mem::Discriminant
. It is undefined behavior to transmute
between DiscriminantKind::Discriminant
and mem::Discriminant
.
