module type SeededHashedType = Hashtbl.SeededHashedType
type t
The type of the hashtable keys.
val equal : t -> t -> bool
The equality predicate used to compare keys.
val hash : int -> t -> int
A seeded hashing function on keys. The first argument is the seed. It must be the case that if equal x y is true, then hash seed x = hash seed y for any value of seed. A suitable choice for hash is the function Hashtbl.seeded_hash below.
