def fromFoldLeft[M[_], A, B](b: B)(f: (B, A) => M[B])(using m: Monad[M]): Fold[M, A, B] { type S = B; }
- Returns
a fold from arguments of a fold left
def fromMonoidMap[M[_], A, O](f: A => O)(using `evidence$2`: Monoid[O], m: Monad[M]): Fold[M, A, O] { type S = O; }
- Returns
a fold which uses a Monoid to accumulate elements
def fromMonoidMapEval[M[_], A, O](f: A => M[O])(using `evidence$3`: Monoid[O], m: Monad[M]): Fold[M, A, O] { type S = O; }
- Returns
a fold which uses a Monoid to accumulate elements
