[−][src]Crate reword
Provides a macro for generating static structures used for value lookup.
reword! { enum Lang: &'static str { struct Hi { const NO = "Hei"; const EN_UK | EN_US = "Hi"; } } } let mut lang = Lang::NO; assert_eq!(lang.reword::<Hi>(), "Hei"); lang = Lang::EN_UK; assert_eq!(lang.reword::<Hi>(), "Hi"); lang = Lang::EN_US; assert_eq!(lang.reword::<Hi>(), "Hi");
The structures generated are not exported out of its module by default.
Use pub
before theenum
keyword to export it.
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. At the moment, the reword macro
can only be used once per module, so if you need to define multiple structures you should
put them in separate submodules.
