NAME

Hashtbl.Make - Functor building an implementation of the hashtable structure.  

Module

Module Hashtbl.Make  

Documentation

Module Make
 :  functor (H : HashedType) -> sig end

Functor building an implementation of the hashtable structure. The functor Hashtbl.Make returns a structure containing a type key of keys and a type 'a t of hash tables associating data of type 'a to keys of type key . The operations perform similarly to those of the generic interface, but use the hashing and equality functions specified in the functor argument H instead of generic equality and hashing.

Parameters:

"H"
