data FastMutableIntMap a

new :: IntMap a -> IO (FastMutableIntMap a)

newEmpty :: IO (FastMutableIntMap a)

insert :: FastMutableIntMap a -> Int -> a -> IO ()

isEmpty :: FastMutableIntMap a -> IO Bool

getFrozenAndClear :: FastMutableIntMap a -> IO (IntMap a)

Make an immutable snapshot of the datastructure and clear it

size :: FastMutableIntMap a -> IO Int

applyPatch :: FastMutableIntMap a -> PatchIntMap a -> IO (IntMap a)

newtype PatchIntMap a

Patch for IntMap which represents insertion or deletion of keys in the mapping. Internally represented by 'IntMap (Maybe a)', where Just means insert/update and Nothing means delete.

Constructors

PatchIntMap (IntMap (Maybe a))

Instances

Functor PatchIntMap

Defined in Reflex.Patch.IntMap

Methods

fmap :: (a -> b) -> PatchIntMap a -> PatchIntMap b

(<$) :: a -> PatchIntMap b -> PatchIntMap a

Foldable PatchIntMap

foldr' :: (a -> b -> b) -> b -> PatchIntMap a -> b

foldl :: (b -> a -> b) -> b -> PatchIntMap a -> b

foldl' :: (b -> a -> b) -> b -> PatchIntMap a -> b

foldr1 :: (a -> a -> a) -> PatchIntMap a -> a

foldl1 :: (a -> a -> a) -> PatchIntMap a -> a

toList :: PatchIntMap a -> [a]

null :: PatchIntMap a -> Bool

length :: PatchIntMap a -> Int

elem :: Eq a => a -> PatchIntMap a -> Bool

Traversable PatchIntMap

Defined in Reflex.Patch.IntMap

Methods

traverse :: Applicative f => (a -> f b) -> PatchIntMap a -> f (PatchIntMap b)

sequenceA :: Applicative f => PatchIntMap (f a) -> f (PatchIntMap a)

mapM :: Monad m => (a -> m b) -> PatchIntMap a -> m (PatchIntMap b)

sequence :: Monad m => PatchIntMap (m a) -> m (PatchIntMap a)

Semigroup (PatchIntMap v)

a <> b will apply the changes of b and then apply the changes of a. If the same key is modified by both patches, the one on the left will take precedence.
