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
.
Operations on Hashtbl
without exceptions.
module Infix : sig ... end
Operations on Hashtbl
