PartialInvariantFunctor

trait PartialInvariantFunctor[F[_]] extends InvariantFunctor[F]

Given a type constructor F, a partial function A => Validated[B] and a total function B => A, turns an F[A] into an F[B].

A partial invariant functor is an invariant functor whose covariant transformation function is total (ie, A => Valid[B]).

Abstract Value Members

  1. abstract def xmapPartial[A, B](fa: F[A], f: (A) => Validated[B], g: (B) => A): F[B]

    Transforms an F[A] value into an F[B] value given a partial function from A to B, and a total function from B to A.

    Transforms an F[A] value into an F[B] value given a partial function from A to B, and a total function from B to A.

    This is useful to refine the type A into a possibly smaller type B.
