// 🦀 Example of spawning thread and
// waiting for it to finish its work.
use std::thread::spawn;
fn main() {
  let work = || println!("Doing thread work");    // Define a Rust closure that will perform some work in a thread
  let handle = spawn(work);                       // spawn() function kicks off new thread, using closure
  _ = handle.join();                              // .join() waits for thread to finish
