Struct Barrier 

pub struct Barrier { /* private fields */ }

Implementations

impl Barrier

pub fn new(num: usize, key: &str, client: Client) -> Self

pub fn wait(&mut self) -> BarrierWaitResult

Blocks the current thread until all threads have rendezvoused here.

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

A single (arbitrary) thread will receive a BarrierWaitResult that returns true from BarrierWaitResult::is_leader() when returning from this function, and all other threads will receive a result that will return false from BarrierWaitResult::is_leader().

The barrier needs to be mutable, because it guarantees that the barrier is only used once in thread. If you want to synchronize threads, you need to create a new barrier for each thread, so it has its own uuid.

Examples

use dtypes::redis::sync::Barrier;
use std::thread;

let n = 10;
let mut handles = Vec::with_capacity(n);
let client = redis::Client::open("redis://localhost:6379").unwrap();
for _ in 0..n {
    // The same messages will be printed together.
    // You will NOT see any interleaving.
    let mut barrier = Barrier::new(n, "barrier_doc_test2", client.clone());
    handles.push(thread::spawn(move|| {
        println!("before wait");
        barrier.wait();
        println!("after wait");
    }));
}
// Wait for other threads to finish.
for handle in handles {
    handle.join().unwrap();
}

Trait Implementations

impl Drop for Barrier

fn drop(&mut self)
