Hashtbl.MakeSeeded - Functor building an implementation of the hashtable structure.

Module Hashtbl.MakeSeeded

Module MakeSeeded
: functor (H : SeededHashedType) -> sig end

Functor building an implementation of the hashtable structure. The functor Hashtbl.MakeSeeded 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 seeded hashing and equality functions specified in the functor argument H instead of generic equality and hashing. The create operation of the result structure supports the ~random optional parameter and returns randomized hash tables if ~random:true is passed or if randomization is globally on (see Hashtbl.randomize ).
