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 anF[B]value given a partial function fromAtoB, and a total function fromBtoA.Transforms an
F[A]value into anF[B]value given a partial function fromAtoB, and a total function fromBtoA.This is useful to refine the type
Ainto a possibly smaller typeB.- See also
