Enum GenericUsage 

enum GenericUsage {
    Absent,
    Bare,
    InContainer(TypePath),
}

How a generic type parameter T appears in a type.

Variants

Absent

T does not appear in this type.

Bare

T appears bare (possibly wrapped in Option or Result).

InContainer(TypePath)

T appears inside a container type (e.g. DatumList<'a, T>, Array<'a, T>). The stored syn::TypePath is the container with T erased to Datum<'a>.
