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:
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 LF[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.
