foldl' :: (a -> b -> a) -> a -> IntMap b -> a
containers Data.IntMap.Internal Data.IntMap.Lazy Data.IntMap.Strict Data.IntMap.Strict.Internal
A strict version of foldl. Each application of the operator is evaluated before using the result in the next application. This function is strict in the starting value.
foldl' :: (a -> Key -> a) -> a -> IntSet -> a
containers Data.IntSet Data.IntSet.Internal
A strict version of foldl. Each application of the operator is evaluated before using the result in the next application. This function is strict in the starting value.
foldl' :: (a -> b -> a) -> a -> Map k b -> a
containers Data.Map.Internal Data.Map.Lazy Data.Map.Strict Data.Map.Strict.Internal
A strict version of foldl. Each application of the operator is evaluated before using the result in the next application. This function is strict in the starting value.
foldl' :: (a -> b -> a) -> a -> Set b -> a
containers Data.Set Data.Set.Internal
A strict version of foldl. Each application of the operator is evaluated before using the result in the next application. This function is strict in the starting value.
