Arguments

:: (Applicative f, Gettable f)

=> Int

n

-> Getting (Endo [a]) s s a a

-> LensLike f s s [a] [a]

Obtain a Fold by splitting another Fold, Lens, Getter or Traversal into length-n pieces.

 chunkingOf :: Int -> Fold s a -> Fold s [a]

splittingPlaces :: (Applicative f, Gettable f, Integral n) => [n] -> Getting (Endo [a]) s s a a -> LensLike f s s [a] [a]

Obtain a Fold by splitting another Fold, Lens, Getter or Traversal into chunks of the given lengths, .

 splittingPlaces :: Integral n => [n] -> Fold s a -> Fold s [a]

splittingPlacesBlanks :: (Applicative f, Gettable f, Integral n) => [n] -> Getting (Endo [a]) s s a a -> LensLike f s s [a] [a]

Obtain a Fold by splitting another Fold, Lens, Getter or Traversal into chunks of the given lengths. Unlike splittingPlaces, the output Fold will always be the same length as the first input argument.
