Missing code in Server file

Missing code section in Server

It seems at some point a section of code was omitted "to be done", but never got added.
Obiously, the content of the Ok() block is the serve function defined in the same file, but I would like to see how you had implemented it.

Thanks for writing this interesting book!

Relevant code: Line 43 to 67 in the complete_blockchain/src/server.rs file.

    pub fn run(&self, addr: &str) {
        let listener = TcpListener::bind(addr).unwrap();

        if addr.eq(CENTERAL_NODE) == false {
            let best_height = self.blockchain.get_best_height();
            send_version(CENTERAL_NODE, best_height);
        }
        for stream in listener.incoming() {
            let blockchain = self.blockchain.clone();
            thread::spawn(|| match stream {
                Ok(stream) => {
                    ...
                }
                Err(e) => {
                    ...
                }
            });
        }
    }
