Rust provides a mechanism for spawning native OS threads via the spawn
function, the argument of this function is a moving closure.
use std::thread;
static NTHREADS: i32 = 10;
// This is the `main` thread
fn main() {
// Make a vector to hold the children which are spawned.
let mut children = vec![];
for i in 0..NTHREADS {
// Spin up another thread
children.push(thread::spawn(move || {
println!("this is thread number {}", i)
}));
}
for child in children {
// Wait for the thread to finish. Returns a result.
let _ = child.join();
}
}
