rust armanazi thread multi arc mutex

To use multi-threading in Rust with the arc and mutex modules, you can follow these steps:

1. Import the necessary modules:

use std::sync::{Arc, Mutex};
use std::thread;

1. Create a shared data structure using Arc and Mutex:

let shared_data = Arc::new(Mutex::new(0));

1. Spawn multiple threads and access the shared data:

let mut handles = vec![];

for _ in 0..10 {
    let shared_data = Arc::clone(&shared_data);

    let handle = thread::spawn(move || {
        let mut data = shared_data.lock().unwrap();
        *data += 1;
    });

    handles.push(handle);
}

for handle in handles {
    handle.join().unwrap();
}

In this example, we create a shared data structure shared_data using Arc and Mutex. We then spawn 10 threads, each of which locks the Mutex, increments the shared data, and releases the lock. Finally, we wait for all the threads to finish using join().

This approach ensures that only one thread can access the shared data at a time, preventing data races and ensuring thread safety.

I hope this helps! Let me know if you have any further questions.
