Redis使用一种名为RESP（REdis Serialization Protocol）的协议，这是一种二进制安全的协议，旨在序列化数据结构。它不像HTTP那样只是纯文本，所以简单地从TCP流中阅读行并不总是能正确地执行Redis命令。

use std::io::{self, BufRead, BufReader};
use std::net::TcpStream;

fn handle_connection(mut stream: TcpStream) {
    let mut buf_reader = BufReader::new(&mut stream);

    loop {
        let mut line = String::new();
        match buf_reader.read_line(&mut line) {
            Ok(0) => break, // End of stream
            Ok(_) => {
                if line.starts_with("*") {
                    // Handle Redis command
                    // You will need to implement proper RESP parsing here
                    println!("Redis command: {}", line.trim());
                } else {
                    // Not a Redis command or end of command
                    break;
                }
            }
            Err(e) => {
                eprintln!("Failed to read from stream: {}", e);
                break;
            }
        }
    }
}
