Crate reword

Provides a macro to generate structures used for value lookup.

reword::reword! {
    enum Lang: &'static str {
        fn hi {
            NO = "Hei";
            EN_UK | EN_US = "Hi";
        }

        fn fall {
            NO = "Høst";
            EN_UK = "Autumn";
            EN_US = "Fall";
        }
    }
}

let mut lang = Lang::NO;
assert_eq!(lang.hi(), "Hei");
assert_eq!(lang.fall(), "Høst");
lang = Lang::EN_UK;
assert_eq!(lang.hi(), "Hi");
assert_eq!(lang.fall(), "Autumn");
lang = Lang::EN_US;
assert_eq!(lang.hi(), "Hi");
assert_eq!(lang.fall(), "Fall");

Attributes can be attached to both the enum and the methods generated. The Copy, Clone, Debug, Eq, PartialEq, Ord, PartialOrd, and Hash traits are automatically derived for the enum using the derive attribute.
