Discord.Internal.Gateway.EventLoop

Description

Provides logic code for interacting with the Discord websocket gateway. Realistically, this is probably lower level than most people will need

Synopsis

data GatewayException
data ConnLoopState
- = ConnStart
- | ConnClosed
- | ConnReconnect Auth Text Integer
connect :: (Connection -> IO a) -> IO a
type DiscordHandleGateway = (Chan (Either GatewayException Event), Chan GatewaySendable)
connectionLoop :: Auth -> DiscordHandleGateway -> Chan Text -> IO ()
getPayloadTimeout :: Connection -> Int -> Chan Text -> IO (Either ConnectionException GatewayReceivable)
getPayload :: Connection -> Chan Text -> IO (Either ConnectionException GatewayReceivable)
heartbeat :: Chan GatewaySendable -> Int -> IORef Integer -> IO ()
setSequence :: IORef Integer -> Integer -> IO ()
data ConnectionData = ConnData {
- connection :: Connection
- connSessionID :: Text
- connAuth :: Auth
- connChan :: Chan (Either GatewayException Event)
}
startEventStream :: ConnectionData -> Int -> Integer -> Chan GatewaySendable -> Chan Text -> IO ConnLoopState
eventStream :: ConnectionData -> IORef Integer -> Int -> Chan GatewaySendable -> Chan Text -> IO ConnLoopState
