在Debian上使用Rust进行异步编程,可参考以下步骤:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
安装Rust,安装完成后使用source $HOME/.cargo/env
将Rust添加到PATH环境变量。cargo new
命令创建新的Rust项目,如cargo new async_project
。Cargo.toml
文件中添加异步运行时库,如Tokio,添加内容为[dependencies] tokio = { version = "1", features = ["full"] }
。async/await
语法编写异步代码,例如:use tokio::net::TcpListener;
use tokio::prelude::*;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
let listener = TcpListener::bind("127.0.0.1:8080").await?;
loop {
let (mut socket, _) = listener.accept().await?;
tokio::spawn(async move {
let mut buf = [0; 1024];
match socket.read(&mut buf).await {
Ok(_) => {
if socket.write_all(b"Hello, world!\n").await.is_err() {
eprintln!("Failed to write to socket");
}
}
Err(e) => {
eprintln!("Failed to read from socket: {:?}", e);
}
}
});
}
}
cargo run
命令编译并运行程序。
