  4. implicit def ApplyFold[R, T]: Apply[[γ$10$]Fold[R, T, γ$10$]]

    Apply instance

    Apply instance

    This means that we can write:

    val mean: Fold[Int, Int] = (sum |@| count)(_ / _)

    An Apply instance is also a Functor instance so we can write:

    val meanTimes2 = mean.map(_ * 2)

  5. def CobindFold[R, T]: Cobind[[γ$20$]Fold[R, T, γ$20$]]

    Cobind instance

  6. implicit def ComposeFold[R]: Compose[[β$16$, γ$17$]Fold[R, β$16$, γ$17$]]

    A Fold can be turned into a Compose

    A Fold can be turned into a Compose

    This allows us to write:

    val scans = sum compose list

  7. implicit def MonoidSink[R, A]: Monoid[Fold[R, A, Unit]]
  8. implicit def ProfunctorFold[R]: Profunctor[[β$12$, γ$13$]Fold[R, β$12$, γ$13$]]

    Profunctor instance

    Profunctor instance

    This is especially useful because we can "map" on the input element

    val doubleSum = fromMonoid[Double] // sum all elements val roundedDoubleSum = doubleSum.mapfst(_.round)
