Anyone using custom transports for gRPC-go?

[jeremy...@gmail.com]

I've been able to successfully use a custom transport (by implementing the net.Listener standard interface) and passing it into the Server.Serve(...) method; however, at the moment, it's fairly useless because gRPC clients require a grpc.ClientConn instance on creation.


Is there any documentation on how clients/servers use this connection object? I'd imagine the functionality exposed by the standard interface (net.Conn) is really all that's necessary for gRPC (i.e. open/close/read/write). I'd really like to be able to use a standard interface to swap out net.Listener/net.Conn implementations without having to completely rewrite the RPC.

To be clear, It seems you implemented a net.Listener instead of a transport. To implement a custom client/server transport, it is needed to implement grpc.ClientTransport/ServerTransport interface. We will support multiple transports but won't accept the transport impl externally unfortunately.
