Documentation

       Module type HashedType
        = sig end

       The input signature of the functor MoreLabels.Hashtbl.Make .

       type t

       The type of the hashtable keys.

       val equal : t -> t -> bool

       The equality predicate used to compare keys.

       val hash : t -> int

       A  hashing  function  on  keys. It must be such that if two keys are equal according to equal , then they
       have identical hash values as computed by hash .  Examples: suitable ( equal , hash ) pairs for arbitrary
       key types include

       -        ( (=) , MoreLabels.Hashtbl.HashedType.hash  )  for  comparing  objects  by  structure  (provided
       objects do not contain floats)

       -         (  (fun x y -> compare x y = 0) , MoreLabels.Hashtbl.HashedType.hash ) for comparing objects by
       structure and handling nan correctly

       -        ( (==) , MoreLabels.Hashtbl.HashedType.hash ) for comparing objects by physical  equality  (e.g.
       for mutable or cyclic objects).
