Trait has::Has

pub trait Has<T> {
    fn get_ref(&self) -> &T;
}

Trait to model a "has a" relationship between implementing structs and the generic parameter provided. This trait provides only a function to retrieve a non-mutable reference to the contained object. If a mutable reference is desired instead, use HasMut.
