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 seeded_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 `seeded_hash seed x = seeded_hash seed y`

for any value of
`seed`

. A suitable choice for `seeded_hash`

is the function
`Hashtbl.seeded_hash`

below.
