Turns a CellDecoder into a RowDecoder, for rows that contain a single value.
Turns a CellDecoder into a RowDecoder, for rows that contain a single value.
This provides default behaviour for RowDecoder.field by decoding the first cell.
RowDecoder[Int].decode(Seq("123", "456", "789")) res1: DecodeResult[Int] = Right(123)
