Struct std::sync::BarrierExperimental [-]  [+] [src]

pub struct Barrier {
    // some fields omitted
}

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

fn main() { use std::sync::{Arc, Barrier}; use std::thread::Thread; 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. Thread::spawn(move|| { println!("before wait"); c.wait(); println!("after wait"); }).detach(); } }
use std::sync::{Arc, Barrier};
use std::thread::Thread;

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.
    Thread::spawn(move|| {
        println!("before wait");
        c.wait();
        println!("after wait");
    }).detach();
}

Methods

impl Barrier

fn new(n: uint) -> Barrier

Create a new barrier that can block a given number of threads.

A barrier will block n-1 threads which call wait and then wake up all threads at once when the nth thread calls wait.

fn wait(&self)

Block the current thread until all threads has rendezvoused here.

Barriers are re-usable after all threads have rendezvoused once, and can be used continuously.
