How to do it...

Follow these steps to see how to move memory between threads:

1. Use cargo new simple-threads to create a new application project and open the directory in Visual Studio Code.
2. Edit src/main.rs and spawn a simple thread that does not move data into its scope. Since it's the simplest form of a thread, let's print something to the command line and wait:

use std::thread;use std::time::Duration;fn start_no_shared_data_thread() -> thread::JoinHandle<()> {    thread::spawn(|| {        // since we are not using a parent scope variable in here        // no move is required        println!("Waiting for three seconds.");        thread::sleep(Duration::from_secs(3));         println!("Done")    })}

3. Now, let's call the new function from within fn main(). Replace the hello world ...
