Thread
use std::thread;
By default, when the main thread of a Rust program completes, all spawned threads are shut down, whether or not they have finished running.
Waiting for All Threads to Finish Using join Handles
use std::thread;
use std::time::Duration;
fn main() {
let handle = thread::spawn(|| {
for i in 1..10 {
println!("hi number {} from the spawned thread!", i);
thread::sleep(Duration::from_millis(1));
}
});
handle.join().unwrap(); // put it here like waitGroup
for i in 1..5 {
println!("hi number {} from the main thread!", i);
thread::sleep(Duration::from_millis(1));
}
handle.join().unwrap();
}move
move, to indicate that the closure is going to take ownership of the values it’s capturing.
