Enums

Enums are types with a set of possible values. They are defined using the enum macro from base.orb.

enum CardSuite {
    Spades
    Hearts
    Clubs
    Diamonds
};

Values of this enum can then be referred to as, eg. CardSuite.Spades.

By default, the underlying type of an enum is i32, the first value is 0, and each value other than first is one greater than the previous one.

You may override these defaults.

enum HttpStatus u32 {
    (Ok 200)
    Created
    Accepted
    (BadRequest 400)
    Unauthorized
    PaymentRequired
    Forbidden
    NotFound
    (InternalError 500)
};

You can get the number of different values in your enum using base.getEnumSize.

    std.println (base.getEnumSize CardSuite); # prints 4
