传递给新线程的变量的生命周期

编译此程序时遇到问题:

use std::env;
use std::sync::mpsc;
use std::thread;
use std::time::Duration;

fn main() {
    let args: Vec<_> = env::args().skip(1).collect();

    let (tx, rx) = mpsc::channel();

    for arg in &args {
        let t = tx.clone();

        thread::spawn(move || {
            thread::sleep(Duration::from_millis(50));
            let _new_arg = arg.to_string() + "foo";
            t.send(arg);
        });
    }

    for _ in &args {
        println!("{}", rx.recv().unwrap());
    }
}

我从命令行读取所有参数,并模拟对线程中的每个参数做一些工作.然后我打印出这项工作的结果,我使用一个频道.

   = note: borrowed value must be valid for the static lifetime...

let new_arg = arg.to_string() + "foo";
t.send(arg);

crossbeam::scope(|scope| {
    scope.spawn(|| {
        println!("Hello from a scoped thread!");
    });
});
