module Make: functor (H : HashedType) -> S
with type key = H.t
and type 'a t = 'a Hashtbl.Make(H).t
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.
