Shape

abstract class Shape[-Mixed_, Unpacked_, Packed_] extends AnyRef

A type class that encodes the unpacking Mixed => Unpacked of a Query[Mixed] to its result element type Unpacked and the packing to a fully packed type Packed, i.e. a type where everything which is not a transparent container is wrapped in a Column[_].

Example:

- Mixed: (Column[Int], Column[(Int, String)], (Int, Option[Double])) - Unpacked: (Int, (Int, String), (Int, Option[Double])) - Packed: (Column[Int], Column[(Int, String)], (Column[Int], Column[Option[Double]])) - Linearized: (Int, Int, String, Int, Option[Double])

    Build a packed representation from the shape and the TypeMappers alone.

    Build a packed representation from the shape and the TypeMappers alone. This method is not available for shapes where Mixed and Unpacked are different types.
