Macro big_enum_set::big_enum_set

macro_rules! big_enum_set {
    ( $( $value:path )|* $( | )? ) => { ... };
}

Creates a BigEnumSet literal, which can be used in const contexts.

The syntax used is big_enum_set!(Type::A | Type::B | Type::C). Each variant must be of the same type, or a error will occur at compile-time.

Examples

const CONST_SET: BigEnumSet<Enum> = big_enum_set!(Enum::A | Enum::B);
assert_eq!(CONST_SET, Enum::A | Enum::B);

This macro is strongly typed. For example, the following will not compile:

let type_error = big_enum_set!(Enum::A | Enum2::B);
