[−][src]Crate reword
Provides a macro to generate structures used for constant value lookup.
reword! { enum Lang: &'static str { struct Hi { const NO = "Hei"; const EN_UK | EN_US = "Hi"; } struct Humor { const NO | EN_US = "Humor"; const EN_UK = "Humour"; } } } let mut lang = Lang::NO; assert_eq!(lang.get::<Hi>(), "Hei"); assert_eq!(lang.get::<Humor>(), "Humor"); lang = Lang::EN_UK; assert_eq!(lang.get::<Hi>(), "Hi"); assert_eq!(lang.get::<Humor>(), "Humour"); lang = Lang::EN_US; assert_eq!(lang.get::<Hi>(), "Hi"); assert_eq!(lang.get::<Humor>(), "Humor");
Attributes can be attached to both the enum
and the structures generated.
The Copy
, Clone
, Debug
, Eq
, PartialEq
, Ord
, PartialOrd
, and Hash
traits are
automatically derived for the types using the derive attribute.
The structures generated are not exported out of its module by default.
Use pub
before theenum
keyword to export it.
