Struct bitflags::__core::sync::Barrier

pub struct Barrier {
    // some fields omitted
}

[−] Expand description

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

use std::sync::{Arc, Barrier};
use std::thread;

let mut handles = Vec::with_capacity(10);
let barrier = Arc::new(Barrier::new(10));
for _ in 0..10 {
    let c = barrier.clone();
    // The same messages will be printed together.
    // You will NOT see any interleaving.
    handles.push(thread::spawn(move|| {
        println!("before wait");
        c.wait();
        println!("after wait");
    }));
}
// Wait for other threads to finish.
for handle in handles {
    handle.join().unwrap();
}
