示例
main.rs
use mini_redis::{Connection, Frame};
use tokio::net::{TcpListener, TcpStream};
#[tokio::main]
async fn main() -> mini_redis::Result<()> {
let listener = TcpListener::bind("127.0.0.1:6379").await?;
loop {
let (socket, address) = listener.accept().await?;
println!("客户端: {}", address);
// 提交任务
tokio::spawn(process(socket)).await??;
}
}
async fn process(socket: TcpStream) -> mini_redis::Result<()> {
// Connection 是 mini redis 定义的内容
let mut connection = Connection::new(socket);
if let Some(frame) = connection.read_frame().await? {
println!("GOT: {:?}", frame);
let response = Frame::Error("unimplemented".to_string());
connection.write_frame(&response).await.unwrap();
}
Ok(())
}
总结
分离接收客户端和处理客户端传递的数据。
