Macro multi_eq_make_trait

Macro to define a comparison trait

The format of the generated trait is the same as PartialEq, but with potentially different names.

Parameters:

• vis - optional visibility specifier
• trait_name - name of the trait being defined
• method_name - name of the method in the trait

Example:

use multi_eq::*;

multi_eq_make_trait!(pub, PublicCustomEq, custom_eq);
multi_eq_make_trait!(PrivateCustomEq, eq);

Generated code:

pub trait PublicCustomEq {
    fn custom_eq(&self, other: &Self) -> bool;
}

trait PrivateCustomEq {
    fn eq(&self, other: &Self) -> bool;
}
