Macro dyn_sized::derive_DynSized

macro_rules! derive_DynSized {
    ($Trait:ty) => { ... };
    ($Trait:ty, $($args:tt)+ ) => { ... };
}

Derives the DynSized trait for trait objects.

To use:

#[macro_use] extern crate dyn_sized;
trait MyTrait {}
derive_DynSized!(MyTrait);

trait MyGenericTrait<'a, T: 'a> {
    fn foo(&'a self) -> T;
}
// type arguments for the impl go after the trait object type.
derive_DynSized!(MyGenericTrait<'a, T>, 'a, T: 'a);
