object Tuple2

Stage projections for Scala's standard scala.Tuple2 type.

Each projection extracts one element of a pair (A, B) and always yields h8io.stages.Yield.Some with h8io.stages.Status.Success, because a tuple always has both elements.

Example:

val fstStage = Tuple2.Left[String]   // Stage[(String, Any), String, Nothing]
val sndStage = Tuple2.Right[Int]     // Stage[(Any, Int), Int, Nothing]

  19. object Left extends LeftProjection[scala.Tuple2]

    Extracts the first element (_1) of a (A, B) pair.

    Extracts the first element (_1) of a (A, B) pair.

    Use Tuple2.Left[T] to get a typed Projection[(T, Any), T].

  20. object Right extends RightProjection[scala.Tuple2]

    Extracts the second element (_2) of a (A, B) pair.

    Extracts the second element (_2) of a (A, B) pair.

    Use Tuple2.Right[T] to get a typed Projection[(Any, T), T].
