rustHow to check if a thread is finished in Rust?

To check if a thread is finished in Rust, you can use the join() method on the thread handle. This will block the current thread until the thread handle is finished.

Example code

let handle = thread::spawn(|| {
    println!("Hello from a thread!");
});

handle.join().expect("The thread being joined has panicked");

Output example

Hello from a thread!

The code above creates a thread handle with the thread::spawn() method, and then calls the join() method on the handle. This will block the current thread until the thread handle is finished. The expect() method is used to handle any panics that may occur in the thread.
