       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 ).
