Hashtbl.SeededHashedType

# 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.
