sealed abstract class ContravariantCoyoneda[F[_], A] extends Serializable
The free contravariant functor on F
. This is isomorphic to F
as long as F
itself is a
contravariant functor. The function from F[A]
to ContravariantCoyoneda[F,A]
exists even when
F
is not a contravariant functor. Implemented using a List of functions for stack-safety.
