In Rust, things are similar to the C++ approach, where we have the std::thread module with the spawn() function. This function will receive a closure or a pointer to a function and execute it. It will return a handle to the thread, and we will be able to manage it from outside. Let's see how this works:
use std::thread;fn main() { println!("Before the thread!"); let handle = thread::spawn(|| { println!("Inside the thread!"); }); println!("After thread spawn!"); handle.join().expect("the thread panicked"); println!("After everything!");}
This will output something similar to this:
The Inside the thread! and After thread spawn! ...
