Function similar to Ecto.Query.first/2 that looks for Ecto.Query.N'th/2

I am looking for the Query that is similar to the Ecto.Query.first/2, but fetch out the Nth record, something like Ecto.Query.N’th/2

#2

offset + limit does that. Ecto.Query.first does nothing else, but wrap it in a convenient function.

User |> order_by(asc: :id) |> limit(1) |> offset(10) |> Repo.one

Will retrieve the 10th user as sorted by id.

Yeah agreed. Do you know of a solid solution that makes it easy to do keyset pagination AND the ability to sort the whole collection by many different columns?
