24       The type of the hashtable keys.

28       val equal : t -> t -> bool

30       The equality predicate used to compare keys.

34       val hash : t -> int
35
36       A  hashing function on keys. It must be such that if two keys are equal
37       according to equal , then they have identical hash values  as  computed
38       by  hash .  Examples: suitable ( equal , hash ) pairs for arbitrary key
39       types include
40
41       -        ( (=) , Hashtbl.hash )  for  comparing  objects  by  structure
42       (provided objects do not contain floats)
43
44       -         ( (fun x y -> compare x y = 0) , Hashtbl.hash ) for comparing
45       objects by structure and handling Pervasives.nan correctly
46
47       -        ( (==) , Hashtbl.hash )  for  comparing  objects  by  physical
48       equality (e.g. for mutable or cyclic objects).
