Class type

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

module H : HashedType

Override modules

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.
