Expand description

sod::Service implementations to interact with crossbeam queues.

Service Impls

Async

Any of the services can be represented as an AsyncService using [`sod::IntoAsyncService::into_async].

use crossbeam::queue::ArrayQueue;
use sod::{PollService, IntoMutService, Service};
use sod_crossbeam::ArrayQueuePopper;
use std::{sync::Arc, time::Duration};

let q = Arc::new(ArrayQueue::<i32>::new(128));
let async_popper = ArrayQueuePopper::new(Arc::clone(&q)).into_mut();

Blocking

sod::PollService may encapsulate a ArrayQueuePopper or SegQueuePopper to provide a backoff mechanism to avoid busy-spinning the CPU in a poll loop.

use crossbeam::queue::ArrayQueue;
use sod::{idle::backoff, PollService, Service};
use sod_crossbeam::ArrayQueuePopper;
use std::{sync::Arc, time::Duration};

let q = Arc::new(ArrayQueue::<i32>::new(128));
let popper = PollService::new(ArrayQueuePopper::new(Arc::clone(&q)), backoff);

loop {
    println!("received: {}", popper.process(()).unwrap());
}

sod::RetryService may encapsulate a ArrayQueuePusher to block and continuously retry pushing an element to an [ArrayQueue] until it succeeds.

use crossbeam::queue::ArrayQueue;
use sod::{RetryService, Service, idle::yielding};
use sod_crossbeam::ArrayQueuePusher;
use std::sync::Arc;

let q = Arc::new(ArrayQueue::new(128));
let pusher = RetryService::new(ArrayQueuePusher::new(Arc::clone(&q)), yielding);

pusher.process(123).unwrap();
pusher.process(456).unwrap();
