ImpureAp

case class ImpureAp[R, X, A](unions: Unions[R, X], continuation: Continuation[R, Vector[Any], A], last: Last[R] = Last.none[R]) extends Eff[R, A] with Product with Serializable

ImpureAp is a list of independent effects and a pure function creating a value with all the resulting values once all effects have been interpreted.

This essentially models a sequence + map operation but it is important to understand that the list of Union objects can represent different effects and be like: Vector[Option[Int], Future[String], Option[Int]].

Interpreting such an Eff value for a given effect (say Option) consists in:

  • grouping all the Option values,
  • sequencing them
  • pass them to a continuation which will apply the 'map' functions when the other effects (Future in the example above) will have been interpreted

VERY IMPORTANT:

  • this object is highly unsafe
  • the size of the list argument to 'map' must always be equal to the number of unions in the Unions object
  • the types of the elements in the list argument to 'map' must be the exact types of each effect in unions.unions
