一定要用闭包?
感觉有点过了。
use std::thread; use std::time::Duration; fn main() { let v = vec![1, 2, 3]; let handle = thread::spawn(move || { println!("Here's a vector: {:?}", v); for i in 1..10 { println!("hi number {} from the spawned thread!", i); thread::sleep(Duration::from_millis(1)); } }); for i in 1..5 { println!("hi number {} from the main thread!", i); thread::sleep(Duration::from_millis(1)); } handle.join().unwrap(); }
