(** Functional red-black binary trees. *)

(** {6 Overview}
    
    This module implements functional sets and maps based on red-black binary
    trees.  This permits trees that can be used as an alternative to the [Set]
    and [Map] modules in the Ocaml standard library.  For many operations on
    sets and maps, red-black binary trees give better performance that the
    balanced trees in the standard library (though some applications may see
    better performance with the standard modules).

(** {6 Module} *)

(** A functor that produces a module of type [Cf_set] to represent sets with
    the element type described by [E].
*)
module Set(E: Cf_ordered.Total_T): Cf_set.T with module Element = E

(** A functor that produces a module of type [Cf_map] to represent maps with
    keys of the type described by [K].
*)
module Map(K: Cf_ordered.Total_T): Cf_map.T with module Key = K
