`Hashtbl.SeededHashedType`

The input signature of the functor `MakeSeeded`

.

`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 `Stdlib.Hashtbl.seeded_hash`

below.
