  1. foldl :: (a -> b -> a) -> a -> NEMap k b -> a

    nonempty-containers Data.Map.NonEmpty

    O(n). Fold the values in the map using the given left-associative binary operator, such that foldl f z == foldl f z . elems. 

    elemsList = reverse . foldl (flip (:)) []

    let f len a = len + (length a)
foldl f 0 (fromList ((5,"a") :| [(3,"bbb")])) == 4

  2. foldl :: (a -> b -> a) -> a -> NEMap k b -> a

    nonempty-containers Data.Map.NonEmpty.Internal

    O(n). Fold the values in the map using the given left-associative binary operator, such that foldl f z == foldl f z . elems. 

    elemsList = reverse . foldl (flip (:)) []

    let f len a = len + (length a)
foldl f 0 (fromList ((5,"a") :| [(3,"bbb")])) == 4

  3. foldl :: (a -> b -> a) -> a -> NESet b -> a

    nonempty-containers Data.Set.NonEmpty

    O(n). Fold the elements in the set using the given left-associative binary operator, such that foldl f z == foldl f z . toAscList. For example, 

    descElemsList set = foldl (flip (:)) [] set

  4. foldl :: (a -> b -> a) -> a -> NESet b -> a

    nonempty-containers Data.Set.NonEmpty.Internal

    O(n). Fold the elements in the set using the given left-associative binary operator, such that foldl f z == foldl f z . toAscList. For example, 

    descElemsList set = foldl (flip (:)) [] set
