17 Functor building an implementation of the hashtable structure. The
18 functor Hashtbl.Make returns a structure containing a type key of keys
19 and a type 'a t of hash tables associating data of type 'a to keys of
20 type key . The operations perform similarly to those of the generic
21 interface, but use the hashing and equality functions specified in the
22 functor argument H instead of generic equality and hashing. Since the
23 hash function is not seeded, the create operation of the result strucā
24 ture always returns non-randomized hash tables.
