-- | Simple Bytestring Packer
data Packer a

-- | Packing result:
--   
--   <ul>
--   <li>PackerOK a -&gt; means the bytestring has been filled with the

--   <li>PackerMore a cache -&gt; a temporary</li>

-- | pack the given packer into the given bytestring

-- | put a storable from the current position in the stream
putStorable :: Storable storable => storable -> Packer ()

-- | put a Bytestring from the current position in the stream
--   
--   If the ByteString ins null, then do nothing
putByteString :: ByteString -> Packer ()

-- | Will put the given storable list from the current position in the
--   stream to the end.
--   
--   This function will fail with not enough storage if the given storable
--   can't be written (not enough space)
--   
--   example: &gt; pack (fillList $ [1..] :: Word8) 9 ==&gt; "123456789"
--   &gt; pack (fillList $ [1..] :: Word32) 4 ==&gt; "1000" &gt; pack
--   (fillList $ [1..] :: Word32) 64 -- will work &gt; pack (fillList $
--   [1..] :: Word32) 1 -- will fail (not enough space) &gt; pack (fillList
--   $ [1..] :: Word32) 131 -- will fail (not enough space)
fillList :: Storable storable => [storable] -> Packer ()

-- | fill up from the current position in the stream to the end
--   
--   it is basically: &gt; fillUpWith s == fillList (repeat s)

-- | put Word8 in the current position in the stream
putWord8 :: Word8 -> Packer ()

-- | put Word16 in the current position in the stream /! use Host

putWord16 :: Word16 -> Packer ()

-- | put Word32 in the current position in the stream /! use Host
--   Endianness
putWord32 :: Word32 -> Packer ()

-- | skip some bytes from the current position in the stream
skip :: Int -> Packer ()

-- | skip the size of a storable from the current position in the stream
