## 1. Arc<Mutex<T>> 黄金拍档
在多线程中修改计数器：
```rust
use std::sync::{Arc, Mutex};
use std::thread;
fn main() {
let counter = Arc::new(Mutex::new(0));
let mut handles = vec![];
for _ in 0..10 {
let counter_clone = Arc::clone(&counter);
let handle = thread::spawn(move || {
let mut num = counter_clone.lock().unwrap();
*num += 1;
});
handles.push(handle);
}
for handle in handles {
handle.join().unwrap();
}
println!("最终计数值: {}", *counter.lock().unwrap());
}
```
