  ` Hashes the essential components of this value by feeding them into the
  given hasher.

  Implement this method to conform to the `Hashable` protocol. The
  components used for hashing must be the same as the components compared
  in your type's `==` operator implementation. Call `hasher.combine(_:)`
  with each of these components.
  Important

  In your implementation of `hash(into:)`,
  don't call `finalize()` on the `hasher` instance provided,
  or replace it with a different instance.
  Doing so may become a compile-time error in the future.

  #### Declaration

  Swift

      func hash(into hasher: inout Hasher)
