Deref

A trait for dereferencing a value to provide transparent access to its contents.Implementing this trait allows a type to behave like its inner type, enabling direct access to the inner type's fields.Note: The Deref mechanism is limited and cannot be used to implicitly convert a type to its target type when passing arguments to functions. For example, if you have a function that takes an Inner, you cannot pass an Outer to it even if Outer implements Deref. # Examples

struct Wrapper<T> { inner: T }

impl WrapperDeref<T> of Deref<Wrapper<T>> {
    type Target = T;
    fn deref(self: Wrapper<T>) -> T { self.inner }
}

let wrapped = Wrapper { inner: 42 };
assert!(wrapped.deref() == 42);
