trait PolyFunction[F[_], G[_]]

Natural transformation, turning a polymorphic type into another, whilst keeping the type parameter intact.

Abstract methods

def apply[A](fa: F[A]): G[A]

Concrete methods

final def andThen[H[_]](other: PolyFunction[G, H]): PolyFunction[F, H]
final def unsafeCache(allPossibleInputs: Vector[Existential[F]]): PolyFunction[F, G]

Pre-computes the polyfunction by applying it on a vector of possible inputs.

Pre-computes the polyfunction by applying it on a vector of possible inputs.

Unsafe because calling the resulting polyfunction with an input that wasn't cached will result in an exception.

final def unsafeMemoise: PolyFunction[F, G]

Creates a memoised version of this function.

Creates a memoised version of this function.

Unsafe because it creates mutable state, which is a non-referentially-transparent action (aka a side-effect).
