如何为包装在互斥锁中的结构实现ops::Deref

use std::ops::Deref;
use std::sync::{Mutex, MutexGuard};

struct MyStruct {
    data: i32,
}

impl Deref for MyStruct {
    type Target = i32;

    fn deref(&self) -> &Self::Target {
        &self.data
    }
}

fn main() {
    let my_struct = MyStruct { data: 42 };
    let mutex = Mutex::new(my_struct);

    {
        let guard: MutexGuard<MyStruct> = mutex.lock().unwrap();
        println!("Dereferenced value: {}", *guard);
    } // MutexGuard is automatically released here
}
