Equivalent
Equivalent and Comparable are Rust traits for key comparison in maps.
These may be used in the implementation of maps where the lookup type Q
may be different than the stored key type K.
Q: Equivalent<K>checks for equality, similar to theHashMap<K, V>constraintK: Borrow<Q>, Q: Eq.Q: Comparable<K>checks the ordering, similar to theBTreeMap<K, V>constraintK: Borrow<Q>, Q: Ord.
These traits are not used by the maps in the standard library, but they may
add more flexibility in third-party map implementations, especially in
situations where a strict K: Borrow<Q> relationship is not available.
