module type SeededHashedType = sig .. end
The 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.
