Derive Alias

Provides a way to alias mutliple derives as one:

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; }

You can create multiple aliases at a time:

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; }
