Equivalent

crates.io docs

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 the HashMap<K, V> constraint K: Borrow<Q>, Q: Eq.
  • Q: Comparable<K> checks the ordering, similar to the BTreeMap<K, V> constraint K: 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.
