Documentation
toArray :: ByteString -> Array Word8 Source #
Convert a ByteString to an array of Word8. It can be done in constant
time only for GHC allocated memory. For foreign allocator allocated memory
there is a copy involved.
fromArray :: Array Word8 -> ByteString Source #
Convert an array of Word8 to a ByteString. This function unwraps the
Array and wraps it with ByteString constructors and hence the operation
is performed in constant time.
reader :: Monad m => Unfold m ByteString Word8 Source #
Unfold a strict ByteString to a stream of Word8.
writeN :: MonadIO m => Int -> Fold m Word8 ByteString Source #
Fold a stream of Word8 to a strict ByteString of given size in bytes.
