macro_rules! quick_derive {
    ($input : expr, $trait_path : expr, < $super : ident >, $trait_def : item $(,)
 *) => { ... };
    ($input : expr, $trait_path : expr, < $($super : ident), + $(,) * >,
 $trait_def : item $(,) *) => { ... };
    ($input : expr, $trait_path : expr, $trait_def : item $(,) *) => { ... };
}

A macro for making easy to write proc_macro_derive like deriving trait to enum so long as all variants are implemented that trait.

See crate level documentation for details.
