Macro enumset::enum_set

macro_rules! enum_set {
    () => { ... };
    ($enum_name:ty, $($value:path)|* $(|)*) => { ... };
}

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

The format used is enum_set!(Type, Type::A | Type::B | Type::C), where Type is the type of the variants that are expected to follow. When the nightly feature is enabled, that parameter can be omitted.

Examples

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