error[E0382]: use of moved value: `counter`
--> src/main.rs:9:36

...
9 | let handle = thread::spawn(move || {
| ^^^^^^^ value moved into closure here, in previous iteration of loop
10 | let mut num = counter.lock().unwrap();
| ------- use occurs due to use in closure
error: aborting due to previous error
