Derive Alias

提供了一种将多个derive别名合并为一个的方法

use derive_alias::derive_alias;

// Generates a macro (`derive_cmp`) that will attach the listed derives to a given item
derive_alias! {
    derive_cmp => #[derive(Eq, PartialEq, Ord, PartialOrd)]
}

// Attach the derives to `Foo`
derive_cmp! { struct Foo; }

您可以同时创建多个别名

use derive_alias::derive_alias;

derive_alias! {
    derive_cmp => #[derive(Eq, PartialEq, Ord, PartialOrd)],
    derive_other => #[derive(Copy, Clone)]
}

derive_cmp! { struct Foo; }
derive_other! { struct Bar; }
