May I have a Unix domain socket example?

[Magicloud]

Sorry if this is too much to ask. My code does not work with error the connection to the server was already shutdown and I could not figure out how to fix.

The server code:

            tokio::spawn({
                let uds = tarpc::serde_transport::unix::listen(&cli.uds, Bincode::default).await?;
                let mut perm = fs::metadata(&cli.uds).await?.permissions();
                perm.set_mode(perm.mode() | 0o222); // chmod a+w
                fs::set_permissions(&cli.uds, perm).await?;

                uds.filter_map(|x| ready(x.ok()))
                    .map(move |trans| {
                        server::BaseChannel::with_defaults(trans)
                            .execute(
                                Server {
                                    db: y.clone(),
                                    inotify: x.clone(),
                                    records: z.clone(),
                                }
                                .serve(),
                            )
                            .for_each(|x| async {
                                tokio::spawn(x);
                            })
                    })
                    .for_each(|_| async {})
            });

The client code:

            let uds = tarpc::serde_transport::unix::connect(&cli.uds, Bincode::default)
                .await
                .expect("Could not connect to the socket, maybe server is not running.");
            let client = CdlMsgClient::new(client::Config::default(), uds).spawn();

The client error:
