Macro mopafy 

macro_rules! mopafy {
    ($trait_:ident) => { ... };
    ($trait_:ident, only core) => { ... };
}

The macro for implementing all the Any methods on your own trait.

Instructions for use

1. Make sure your trait extends mopa::Any (e.g. trait Trait: mopa::Any { })

2. Mopafy your trait (see the next subsection for specifics).

3. …

4. Profit!

Mopafication techniques

There are three ways of mopafying traits, depending on what libraries you are using.

1. If you are a normal person:

   trait Trait: mopa::Any { }
   mopafy!(Trait);

2. If you are using libcore but not libstd (#![no_std]) or liballoc, write this:

   mopafy!(Trait, only core);

   Unlike the other two techniques, this only gets you the &Any and &mut Any methods; the Box<Any> methods require liballoc.

3. If you are using libcore and liballoc but not libstd (#![no_std]), bring alloc::boxed::Box into scope and use mopafy! as usual:

   use alloc::boxed::Box;
   mopafy!(Trait);
