foldrWithKey package:nonempty-containers

foldrWithKey :: (Key -> a -> b -> b) -> b -> NEIntMap a -> b

nonempty-containers Data.IntMap.NonEmpty

O(n). Fold the keys and values in the map using the given right-associative binary operator, such that foldrWithKey f z == foldr (uncurry f) z . toAscList. For example,

keysList map = foldrWithKey (\k x ks -> k:ks) [] map

foldrWithKey :: (k -> a -> b -> b) -> b -> NEMap k a -> b

nonempty-containers Data.Map.NonEmpty

O(n). Fold the keys and values in the map using the given right-associative binary operator, such that foldrWithKey f z == foldr (uncurry f) z . toAscList. For example,

keysList map = foldrWithKey (\k x ks -> k:ks) [] map

foldrWithKey' :: (Key -> a -> b -> b) -> b -> NEIntMap a -> b

nonempty-containers Data.IntMap.NonEmpty

O(n). A strict version of foldrWithKey. Each application of the operator is evaluated before using the result in the next application. This function is strict in the starting value.
