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]).

    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.
