}

pub type Data {
  Data(key: String, value: String, point: Int)
}

pub fn main() {
  let decoder =
    dynamic.decode3(
      Data,
      dynamic.element(at: 1, of: dynamic.string),
      dynamic.element(at: 2, of: dynamic.string),
      dynamic.element(at: 3, of: dynamic.int),
    )

  let table_name = atom.create_from_string("test")

  let assert Ok(t) =
    named.new(
      name: table_name,
      visibility: named.Public,
      table_type: named.Bag,
      accepts: decoder,
    )

  let _ = insert(t, string("foo"), Data("bar", "baz", 1))
  let _ = insert(t, string("foo"), Data("ayy", "bee", 2))
  let _ = insert(t, string("foo"), Data("cee", "dee", 3))

  lookup(t, string("foo"))
  |> io.debug
}

Running this produces the following output:

Ok([Data("cee", "dee", 3), Data("ayy", "bee", 2), Data("bar", "baz", 1)])
