Methods

gfoldl :: (forall d b. Data d => c (d -> b) -> d -> c b) -> (forall g. g -> c g) -> ByteArray -> c ByteArray #

gunfold :: (forall b r. Data b => c (b -> r) -> c r) -> (forall r. r -> c r) -> Constr -> c ByteArray #

toConstr :: ByteArray -> Constr #

dataTypeOf :: ByteArray -> DataType #

dataCast1 :: Typeable (* -> *) t => (forall d. Data d => c (t d)) -> Maybe (c ByteArray) #

dataCast2 :: Typeable (* -> * -> *) t => (forall d e. (Data d, Data e) => c (t d e)) -> Maybe (c ByteArray) #

gmapT :: (forall b. Data b => b -> b) -> ByteArray -> ByteArray #

gmapQl :: (r -> r' -> r) -> r -> (forall d. Data d => d -> r') -> ByteArray -> r #

gmapQr :: (r' -> r -> r) -> r -> (forall d. Data d => d -> r') -> ByteArray -> r #

gmapQ :: (forall d. Data d => d -> u) -> ByteArray -> [u] #

gmapQi :: Int -> (forall d. Data d => d -> u) -> ByteArray -> u #

gmapM :: Monad m => (forall d. Data d => d -> m d) -> ByteArray -> m ByteArray #

gmapMp :: MonadPlus m => (forall d. Data d => d -> m d) -> ByteArray -> m ByteArray #

gmapMo :: MonadPlus m => (forall d. Data d => d -> m d) -> ByteArray -> m ByteArray #

pokeByteArray :: ByteArray# -> Int -> Int -> Ptr Word8 -> IO (Ptr Word8) Source #

pokeByteString :: ByteString -> Ptr Word8 -> IO (Ptr Word8) Source #

Copy bytestring to given pointer, returns new pointer

unsafeCreateUptoN' :: Int -> (Ptr Word8 -> IO (Int, a)) -> (ByteString, a) Source #

minusPtr :: Ptr a -> Ptr b -> Int #

Computes the offset required to get from the second to the first argument. We have

p2 == p1 `plusPtr` (p2 `minusPtr` p1)
