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.

To take advantage of these overrides, you probably want to or . For instance, to open a version of Hashtbl with exceptionless error management, you may write open Hashtbl, Exceptionless. To locally replace module Hashtbl with a module of the same name but with exceptionless error management, you may write

module Hashtbl = Hashtbl include Exceptionless

module Hashtbl.S.Exceptionless: sig .. end

Operations on Hashtbl without exceptions.

module Hashtbl.S.Labels: sig .. end

Operations on Hashtbl with labels.
