Your array contains machine-sized Ints, which in practice are likely
either 32-bit or 64-bit, while a ByteString is the equivalent of an
array or 8-bit values. So you'll need to somehow convert the Ints to
Word8s. Do you know if you need big or little endian?
A basic approach would be:
* Use freeze to convert your IOArray into an IArray
* Use putIArrayOf and put (from cereal) to generate a Putter value
* Use runPut to generate a ByteString from that

Hi, I need to convert IOArray to bytestring as shown below - import Data.Array.IO import Data.Binary.Put import qualified Data.ByteString.Lazy as BS import Data.Word main = do arr <- newArray (0,9) 0 :: IO (IOArray Int Int) let bs=toByteString arr return () How can I implement the 'toByteString' function?
