Crate reft 

Ref & Mut — Universal AsRef/AsMut bridges for any reference.

Turns &T into AsRef<T> and &mut T into AsMut<T> with zero cost. Perfect for generics that need trait bounds on foreign types.

Structs

Mut

Mutable reference with AsRef<T> + AsMut<T> impls.
Like &mut T, but plays nice with trait bounds.

Own

Owned data with AsRef<T> + AsMut<T> impls.

Ref

Immutable reference with guaranteed AsRef<T> impl.
Works on any type, including those you don’t control.
