Simple thread

• In this case when the main thread does not do "extra job" it is obvious that the other thread did not even have a chance to start working.

use std::thread;

fn main() {
    println!("Before starting: {:?}", thread::current().id());

    thread::spawn(|| {
        println!("In thread {:?}", thread::current().id());
    });

    println!("After ending: {:?}", thread::current().id());
}

Before starting: ThreadId(1)
After ending: ThreadId(1)

• thread
• spawn
