pub trait CastFrom<T> {
    fn cast(t: &T) -> &Self;

    fn cast_mut(t: &mut T) -> &mut Self;
}

Examples

use shred::CastFrom;

trait Foo {
    fn foo1(&self);
    fn foo2(&mut self, x: i32) -> i32;
}

impl<T> CastFrom<T> for Foo
where
    T: Foo + 'static,
{
    fn cast(t: &T) -> &(Foo + 'static) {
        t
    }

    fn cast_mut(t: &mut T) -> &mut (Foo + 'static) {
        t
    }
}
