use std::sync::{Mutex, Arc};
use std::thread;
fn main() {
let counter = Arc::new(Mutex::new(0));
let mut handles = vec![];
for _ in 0..10 {
let new_counter = Arc::clone(&counter);
let handle = thread::spawn(move || {
let mut mun = new_counter.lock().unwrap();
*mun += 1;
});
handles.push(handle);
}
for handle in handles {
handle.join().unwrap();
}
println!("result = {}", *counter.lock().unwrap())
}
