Struct std::sync::Barrier[src]

pub struct Barrier {
    // some fields omitted
}

A barrier enables multiple tasks to synchronize the beginning of some computation.

fn main() { use sync::{Arc, Barrier}; let barrier = Arc::new(Barrier::new(10)); for _ in range(0u, 10) { let c = barrier.clone(); // The same messages will be printed together. // You will NOT see any interleaving. spawn(proc() { println!("before wait"); c.wait(); println!("after wait"); }); } }
use sync::{Arc, Barrier};

let barrier = Arc::new(Barrier::new(10));
for _ in range(0u, 10) {
    let c = barrier.clone();
    // The same messages will be printed together.
    // You will NOT see any interleaving.
    spawn(proc() {
        println!("before wait");
        c.wait();
        println!("after wait");
    });
}
