module type SeededHashedType = sig .. endThe input signature of the functor Hashtbl.MakeSeeded.
type t;
The type of the hashtable keys.
let equal: (t, t) => bool;
The equality predicate used to compare keys.
let 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.
