rustHow to use a callback with a Rust thread?

Using a callback with a Rust thread is a great way to ensure that a task is completed before continuing with the main thread. To do this, you can use the thread::spawn function to create a new thread and pass a closure as an argument. The closure will be executed in the new thread and can be used to call a callback when the task is finished.

Example code

use std::thread;

fn main() {
    let handle = thread::spawn(|| {
        // Do some work
        // Call the callback when done
    });

    // Wait for the thread to finish
    handle.join().unwrap();
}
