}
Expand description

An EnumSetType for which EnumSets have a guaranteed in-memory representation.

An implementation of this trait is generated by using #[derive(EnumSetType)] with the annotation #[enumset(repr = "…")], where … is u8, u16, u32, u64 or u128.

For any type T that implements this trait, the in-memory representation of EnumSet<T> is guaranteed to be Repr. This guarantee is useful for FFI. See the EnumSet documentation under “FFI, Safety and repr” for an example.
