  1. filterMapAux :: (HashMap k v1 -> Maybe (HashMap k v2)) -> (Leaf k v1 -> Maybe (Leaf k v2)) -> HashMap k v1 -> HashMap k v2

    unordered-containers Data.HashMap.Internal

    Common implementation for filterWithKey and mapMaybeWithKey, allowing the former to former to reuse terms.

  2. foldMapWithKey :: Monoid m => (k -> v -> m) -> HashMap k v -> m

    unordered-containers Data.HashMap.Internal

    Reduce the map by applying a function to each element and combining the results with a monoid operation.

  3. fullBitmap :: Bitmap

    unordered-containers Data.HashMap.Internal

    A bitmap with the maxChildren least significant bits set, i.e. 0xFF_FF_FF_FF.

  4. isSubmapOf :: (Hashable k, Eq v) => HashMap k v -> HashMap k v -> Bool

    unordered-containers Data.HashMap.Internal

    Inclusion of maps. A map is included in another map if the keys are subsets and the corresponding values are equal:

    isSubmapOf m1 m2 = keys m1 `isSubsetOf` keys m2 &&
    and [ v1 == v2 | (k1,v1) <- toList m1; let v2 = m2 ! k1 ]
    

    Examples

    >>> fromList [(1,'a')] `isSubmapOf` fromList [(1,'a'),(2,'b')]
    True
    
    >>> fromList [(1,'a'),(2,'b')] `isSubmapOf` fromList [(1,'a')]
    False
    

  5. isSubmapOfBy :: Hashable k => (v1 -> v2 -> Bool) -> HashMap k v1 -> HashMap k v2 -> Bool

    unordered-containers Data.HashMap.Internal

    Inclusion of maps with value comparison. A map is included in another map if the keys are subsets and if the comparison function is true for the corresponding values:

    isSubmapOfBy cmpV m1 m2 = keys m1 `isSubsetOf` keys m2 &&
    and [ v1 `cmpV` v2 | (k1,v1) <- toList m1; let v2 = m2 ! k1 ]
    

    Examples

    >>> isSubmapOfBy (<=) (fromList [(1,'a')]) (fromList [(1,'b'),(2,'c')])
    True
    
    >>> isSubmapOfBy (<=) (fromList [(1,'b')]) (fromList [(1,'a'),(2,'c')])
    False
