Macro relay_event_schema::processor::enum_set

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

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

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

This macro accepts trailing |s to allow easier use in other macros.

Examples

const CONST_SET: EnumSet<Enum> = 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 = enum_set!(Enum::A | Enum2::B);
