# Module Set

    module Set: sig .. end

Sets over ordered types.

This module implements the set data structure, given a total ordering function over the set elements. All operations over sets are purely applicative (no side-effects). The implementation uses balanced binary trees, and is therefore reasonably efficient: insertion and membership take time logarithmic in the size of the set, for instance.

    module type OrderedType = sig .. end

Input signature of the functor `Set.Make`.

    module type S = sig .. end

Output signature of the functor `Set.Make`.

    module Make: functor (Ord : OrderedType) -> S  with type elt = Ord.t

Functor building an implementation of the set structure given a totally ordered type.
