Basic utilities

sourceSocket :: MonadIO m => Socket -> Producer m ByteString

Stream data from the socket.

This function does not automatically close the socket.

Since 0.0.0

sinkSocket :: MonadIO m => Socket -> Consumer ByteString m ()

Stream data to the socket.

This function does not automatically close the socket.

Since 0.0.0

Simple TCP server/client interface.

data AppData :: *

Instances

HasReadWrite AppData

appSource :: (HasReadWrite ad, MonadIO m) => ad -> Producer m ByteString

appSink :: (HasReadWrite ad, MonadIO m) => ad -> Consumer ByteString m ()

appSockAddr :: AppData -> SockAddr

appLocalAddr :: AppData -> Maybe SockAddr

Server

data ServerSettings :: *

Instances

HasPort ServerSettings

HasAfterBind ServerSettings

serverSettings :: Int -> HostPreference -> ServerSettings

runTCPServer :: ServerSettings -> (AppData -> IO ()) -> IO a

runTCPServerWithHandle :: ServerSettings -> ConnectionHandle -> IO a

forkTCPServer :: MonadBaseControl IO m => ServerSettings -> (AppData -> m ()) -> m ThreadId

Fork a TCP Server

Will fork the runGeneralTCPServer function but will only return from this call when the server is bound to the port and accepting incoming connections. Will return the thread id of the server

Since 1.1.4

runGeneralTCPServer :: MonadBaseControl IO m => ServerSettings -> (AppData -> m ()) -> m a

Run a general TCP server

Same as runTCPServer, except monad can be any instance of MonadBaseControl IO.

Note that any changes to the monadic state performed by individual client handlers will be discarded. If you have mutable state you want to share among multiple handlers, you need to use some kind of mutable variables.

Since 1.1.3

Client

data ClientSettings :: *

Instances

HasPort ClientSettings

clientSettings :: Int -> ByteString -> ClientSettings

runTCPClient :: ClientSettings -> (AppData -> IO a) -> IO a

runGeneralTCPClient :: MonadBaseControl IO m => ClientSettings -> (AppData -> m a) -> m a

Run a general TCP client

Same as runTCPClient, except monad can be any instance of MonadBaseControl IO.

Since 1.1.3
