mapDel :: (HasCallStack, MonadIO m) => MapT -> Word32 -> m ()gi-harfbuzz GI.HarfBuzz.Functions Removes key and its stored value from map. Since: 1.7.7
mapGet :: (HasCallStack, MonadIO m) => MapT -> Word32 -> m Word32gi-harfbuzz GI.HarfBuzz.Functions Fetches the value stored for key in map. Since: 1.7.7
mapGetEmpty :: (HasCallStack, MonadIO m) => m MapTgi-harfbuzz GI.HarfBuzz.Functions Fetches the singleton empty MapT. Since: 1.7.7
mapGetPopulation :: (HasCallStack, MonadIO m) => MapT -> m Word32gi-harfbuzz GI.HarfBuzz.Functions Returns the number of key-value pairs in the map. Since: 1.7.7
mapHas :: (HasCallStack, MonadIO m) => MapT -> Word32 -> m Int32gi-harfbuzz GI.HarfBuzz.Functions Tests whether key is an element of map. Since: 1.7.7
mapHash :: (HasCallStack, MonadIO m) => MapT -> m Word32gi-harfbuzz GI.HarfBuzz.Functions Creates a hash representing map. Since: 4.4.0
mapIsEmpty :: (HasCallStack, MonadIO m) => MapT -> m Int32gi-harfbuzz GI.HarfBuzz.Functions Tests whether map is empty (contains no elements). Since: 1.7.7
mapIsEqual :: (HasCallStack, MonadIO m) => MapT -> MapT -> m Int32gi-harfbuzz GI.HarfBuzz.Functions Tests whether map and other are equal (contain the same elements). Since: 4.3.0
mapKeys :: (HasCallStack, MonadIO m) => MapT -> SetT -> m ()gi-harfbuzz GI.HarfBuzz.Functions Add the keys of map to keys. Since: 7.0.0
mapNext :: (HasCallStack, MonadIO m) => MapT -> Int32 -> m (Int32, Int32, Word32, Word32)gi-harfbuzz GI.HarfBuzz.Functions Fetches the next key/value pair in map. Set idx to -1 to get started. If the map is modified during iteration, the behavior is undefined. The order in which the key/values are returned is undefined. Since: 7.0.0
