    Transforms using implicitly available evidence that such a transformation is possible.

    Transforms using implicitly available evidence that such a transformation is possible.

    Typical transformations include converting:

    • an F[L] for some L <: HList to/from an F[CC] for some case class CC, where the types in the case class are aligned with the types in L
    • an F[C] for some C <: Coproduct to/from an F[SC] for some sealed class SC, where the component types in the coproduct are the leaf subtypes of the sealed class.
