This crate provides several macros for deriving some useful methods for unitary enums (i.e. enums where variants do not have payloads) and unary enums.

Feature flags

Using with and without macro_attr!

All of the macros are designed to be used with the macro-attr-2018 crate, though they can be used independent of it. The following:

macro_attr! {
    #[derive(Copy, Clone, Debug, IterVariants!(Vars))]
    enum ItAintRight { BabeNo, NoNo, BoyBoy }
}

can also be written as

#[derive(Copy, Clone, Debug)]
enum ItAintRight { BabeNo, NoNo, BoyBoy }

IterVariants! { (Vars) enum ItAintRight { BabeNo, NoNo, BoyBoy } }
