  assign a local address, or let OS pick one

• clientTargetAddr :: SockAddr

  target address

• clientNoDelay :: Bool

  if we want to use TCP_NODELAY

defaultClientConfig :: ClientConfig

initClient :: HasCallStack => ClientConfig -> Resource TCP

TCP Server

data ServerConfig

A TCP server configuration

Constructors

ServerConfig

Fields

• serverAddr :: SockAddr

  listening address

• serverBackLog :: Int

  listening socket's backlog size

• serverWorker :: TCP -> IO ()

  worker which get an accepted TCP stream, the socket will be closed upon exception or worker finishes.

• serverWorkerNoDelay :: Bool

  if we want to use TCP_NODELAY

defaultServerConfig :: ServerConfig

A default hello world server on localhost:8888

Test it with main = startServer defaultServerConfig, now try nc -v 127.0.0.1 8888

startServer :: HasCallStack => ServerConfig -> IO ()
