Constructors

Transport

Fields

• sendMsg :: ConstMsg -> IO ()

  Send a message

• recvMsg :: IO ConstMsg

  Receive a message

handleTransport :: Handle -> WordCount -> Transport

handleTransport handle limit is a transport which reads and writes messages from/to handle. It uses limit as the traversal limit when reading messages and decoding.

socketTransport :: Socket -> WordCount -> Transport

socketTransport socket limit is a transport which reads and writes messages to/from a socket. It uses limit as the traversal limit when reading messages and decoing.

tracingTransport :: (String -> IO ()) -> Transport -> Transport

tracingTransport log trans wraps another transport trans, loging messages when they are sent or received (using the log function). This can be useful for debugging.
