# Module type MoreLabels.Hashtbl.SeededHashedType

    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.
