    Transforms supplied F[A] to an F[B] 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.

  20. def narrow[A, B](fa: F[A], f: (A) ⇒ Attempt[B], g: (B) ⇒ A): F[B]

    Transforms supplied F[A] to an F[B] using two functions, A => Attempt[B] and B => A.

    Transforms supplied F[A] to an F[B] using two functions, A => Attempt[B] and B => A.

    The supplied functions form an injection from B to A. Hence, converting a F[A] to a F[B] converts from a larger to a smaller type. Hence, the name narrow.

    Transforms supplied F[A] to an F[B] using two functions, A => B and B => Attempt[A].

    The supplied functions form an injection from A to B. Hence, converting a F[A] to a F[B] converts from a smaller to a larger type. Hence, the name widen.
