  11. def fold [M] (t: F[M])(implicit arg0: Monoid[M]): M

    Combine the elements of a structure using a monoid.

  12. def foldLeft [A, B] (t: F[A], z: B, f: (B, A) ⇒ B): B

    Left-associative fold of a structure.

  13. def foldMap [A, M] (t: F[A], f: (A) ⇒ M)(implicit arg0: Monoid[M]): M

    Map each element of the structure to a monoid, and combine the results.

  14. def foldRight [A, B] (t: F[A], z: ⇒ B, f: (A, ⇒ B) ⇒ B): B

    Right-associative fold of a structure.

  15. def foldl1 [A, B] (t: F[A], f: (A, A) ⇒ A): Option[A]

    A variant of 'foldl' that has no base case, and thus may only be applied to non-empty structures.

  16. def foldr1 [A, B] (t: F[A], f: (A, ⇒ A) ⇒ A): Option[A]

    A variant of 'foldr' that has no base case, and thus is undefined for empty structures.
