Capnp.Rpc.Transport

Description

This module provides a Transport type, which provides operations used to transmit messages between vats in the RPC protocol.

Synopsis

data Transport = Transport {
- sendMsg :: Message 'Const -> IO ()
- recvMsg :: IO (Message 'Const)
}
handleTransport :: Handle -> WordCount -> Transport
socketTransport :: Socket -> WordCount -> Transport
tracingTransport :: (String -> IO ()) -> Transport -> Transport

Documentation

data Transport Source #

A Transport handles transmitting RPC messages.

Constructors

Transport
Fields sendMsg :: Message 'Const -> IO () Send a message recvMsg :: IO (Message 'Const) Receive a message

handleTransport :: Handle -> WordCount -> Transport Source #

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 Source #

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 Source #

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.
