Trait Keyed 

pub trait Keyed {
    type Key;
}

Marker trait for keyed collections describing their key type.

This trait is needed to prevent “error[E0207]: the type parameter (...) is not constrained by the impl trait, self type, or predicates” by consuming the type parameter into the associated type Key.
