module Make:
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.

The following modules replace functions defined in Hashtbl
with functions
behaving slightly differently but having the same name. This is by design:
the functions meant to override the corresponding functions of Hashtbl
.
module Exceptionless:sig
..end
Operations on Hashtbl
without exceptions.
module Infix:sig
..end
Infix operators over a BatHashtbl
module Labels:sig
..end
Operations on Hashtbl
with labels.
