       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.  Since the hash function
       is not seeded, the create operation of the result structure always returns  non-randomized
       hash tables.

       Parameters:

       "H"

       val replace : 'a t -> key -> 'a -> unit

       val mem : 'a t -> key -> bool

       val iter : (key -> 'a -> unit) -> 'a t -> unit

       val fold : (key -> 'a -> 'b -> 'b) -> 'a t -> 'b -> 'b

       val length : 'a t -> int

       val stats : 'a t -> Hashtbl.statistics
