如何在rust rocket中获取当前线程(Worker)

use rocket::{get, routes};
use tokio::runtime::Runtime;
use std::thread;

#[get("/current_thread")]
fn current_thread() -> String {
    let runtime = Runtime::new().unwrap();
    let handle = runtime.handle();

    // 获取当前线程ID
    let thread_id = thread::current().id();

    // 获取当前任务所属的线程池信息
    let worker_info = handle.current_worker().unwrap();

    format!(
        "Current Thread ID: {:?}\nWorker ID: {:?}\nWorker Thread ID: {:?}",
        thread_id,
        worker_info.id(),
        worker_info.thread().id()
    )
}

fn main() {
    rocket::ignite()
        .mount("/", routes![current_thread])
        .launch();
}
