  6. def bifoldLeft[A, B, C](fab: Binested[F, G, H, A, B], c: C)(f: (C, A) ⇒ C, g: (C, B) ⇒ C): C

    Collapse the structure with a left-associative function

    Collapse the structure with a left-associative function

    Example:

    scala> import cats.Bifoldable
scala> val fab = (List(1), 2)

Folding by addition to zero:
scala> Bifoldable[Tuple2].bifoldLeft(fab, Option(0))((c, a) => c.map(_ + a.head), (c, b) => c.map(_ + b))
res0: Option[Int] = Some(3)

    With syntax extensions, bifoldLeft can be used like:

    scala> import cats.implicits._
scala> fab.bifoldLeft(Option(0))((c, a) => c.map(_ + a.head), (c, b) => c.map(_ + b))
res1: Option[Int] = Some(3)

  7. def bifoldMap[A, B, C](fab: Binested[F, G, H, A, B])(f: (A) ⇒ C, g: (B) ⇒ C)(implicit C: Monoid[C]): C

    Collapse the structure by mapping each element to an element of a type that has a cats.Monoid

  8. def bifoldRight[A, B, C](fab: Binested[F, G, H, A, B], c: Eval[C])(f: (A, Eval[C]) ⇒ Eval[C], g: (B, Eval[C]) ⇒ Eval[C]): Eval[C]

    Collapse the structure with a right-associative function Right associative lazy bifold on F using the folding function 'f' and 'g'.

    Collapse the structure with a right-associative function Right associative lazy bifold on F using the folding function 'f' and 'g'.

    This method evaluates c lazily (in some cases it will not be needed), and returns a lazy value. We are using (_, Eval[C]) => Eval[C] to support laziness in a stack-safe way. Chained computation should be performed via .map and .flatMap.

    For more detailed information about how this method works see the documentation for Eval[_].

    Example:

    scala> import cats.Bifoldable
scala> val fab = (List(1), 2)

Folding by addition to zero:
scala> val bifolded1 = Bifoldable[Tuple2].bifoldRight(fab, Eval.now(0))((a, c) => c.map(_ + a.head), (b, c) => c.map(_ + b))
scala> bifolded1.value
res0: Int = 3

    With syntax extensions, bifoldRight can be used like:

    scala> import cats.implicits._
scala> val bifolded2 = fab.bifoldRight(Eval.now(0))((a, c) => c.map(_ + a.head), (b, c) => c.map(_ + b))
scala> bifolded2.value
res1: Int = 3
