Module type Hashtbl.SeededHashedType

module type SeededHashedType = sig .. end

The input signature of the functor Hashtbl.MakeSeeded.
Since 4.00.0

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.
