Module Map

module Map: sig .. end
Association tables over ordered types.

This module implements applicative association tables, also known as finite maps or dictionaries, given a total ordering function over the keys. All operations over maps are purely applicative (no side-effects). The implementation uses balanced binary trees, and therefore searching and insertion take time logarithmic in the size of the map.

module type OrderedType = sig .. end
Input signature of the functor Map.Make.
module type S = sig .. end
Output signature of the functor Map.Make.
module Make: 
functor (Ord : OrderedType) -> S with type key = Ord.t
Functor building an implementation of the map structure given a totally ordered type.
