[twincling] Haskell equivalent code ?

[Saifi Khan]

Hi Zubin:

Here is a code fragment from my Erlang server codebase.

<<IPVer:4,
   HLen:4,
   SrvcType:8,
   TotLen:16,
   ID:16,
   Flgs:3,
   FragOff:13,
   TTL:8,
   Proto:8,
   HdrChkSum:16,
   SrcIP:32,
   DestIP:32,
   RestDgram/binary>> = Datagram

i'm using the Erlang Bit syntax expression to pattern match
and extract individual bits in the binary IP datagram.

As you are Haskell expert, could you please share your 
knowledge of how to write this piece of code in Haskell ?

Thank you in advance.


thanks
Saifi.
