[][src]Struct scale_info::TypeDefVariant

pub struct TypeDefVariant<T: Form = MetaForm> { /* fields omitted */ }

A Enum type (consisting of variants).

Examples

A Rust enum, aka tagged union.

enum MyEnum {
    RustAllowsForClikeVariants,
    AndAlsoForTupleStructs(i32, bool),
    OrStructs {
        with: i32,
        named: bool,
        fields: [u8; 32],
    },
    ItIsntPossibleToSetADiscriminantThough,
}

A C-like enum type.

enum Days {
    Monday,
    Tuesday,
    Wednesday,
    Thursday = 42, // Also allows to manually set the discriminant!
    Friday,
    Saturday,
    Sunday,
}

An empty enum (for marker purposes)

enum JustAMarker {}
