-/// Key equivalence trait.
-///
-/// This trait allows hash table lookup to be customized.
-/// It has one blanket implementation that uses the regular `Borrow` solution,
-/// just like `HashMap` and `BTreeMap` do, so that you can pass `&str` to lookup
-/// into a map with `String` keys and so on.
-///
-/// # Contract
-///
-/// The implementor **must** hash like `K`, if it is hashable.
