If I have the following:
make_xword : { rows : Int, cols : Int } -> Xword
import Xword exposing (Xword, make_xword)
type alias InCell =
{ x : Int
, y : Int
, contents : String
}
type alias InXword =
{ rows : Int
, cols : Int
, cells : List InCell
}
to_xword : InXword -> Xword
to_xword input =
make_xword { rows = input.rows, cols = input.cols }
why can I not replace the last function with
to_xword : InXword -> Xword
to_xword input =
make_xword input
since input is a superset of {rows; cols}?
