我有一些 url，然后我将其分成块并同时迭代它们，使用克隆将结果保存在 vec 中：

pub fn collect_parm_list(url_list: Vec<String>) -> Result<Vec<String>, Box<dyn std::error::Error>> {
let shared_id_list = Arc::new(Mutex::new(vec![]));
for chunk in url_list.chunks(20) {
    let mut handles = vec![];
    for url in chunk {
        let id_list = Arc::clone(&shared_id_list);
        let handle = thread::spawn(move || {
            // total: optionSale -> result -> total
            let mut id_list_v = id_list.lock().unwrap();
            id_list_v.push(url.to_string())
        });

        handles.push(handle);
    }
    // Wait for all threads to complete
    for handle in handles {
        handle.join().unwrap();
    }
}

let x = shared_id_list.lock().unwrap();
Ok(x.to_vec())
}

我在借用数据时遇到错误：

url_list does not live long enough borrowed value does not live long enough

在：对于url_list中的块。chunks（20）{
