Parse the request data here. If you have a new subscribe, create a stream with the Schema::create_subscription_stream, and then call SubscriptionStreams::add. You can return a Byte, which will be sent to the client. If it returns an error, the connection will be broken.

fn handle_response(&mut self, id: usize, res: Result<Value>) -> Option<Bytes>

When a response message is generated, you can convert the message to the format you want here.
