That's correct, the only possible improvement is you could use the peek
helper function, but what you have here is fine.
How to detect the end of input in conduit?
Question
I'm trying to use network-conduit as a backend for (patched) HaskellNet's IMAP. One of the required operations is to detect if the stream is open. Currently I'm using
isOpen :: (Monad m) => ConduitM i o m Bool
isOpen = await >>= maybe (return False) ((True <$) . leftover)
Is this correct, or is there a better way?
