Tokio Thread Pool
A library for scheduling execution of futures concurrently across a pool of threads.
Note: This library isn't quite ready for use.
Why not Rayon?
Rayon is designed to handle parallelizing single computations by breaking them into smaller chunks. The scheduling for each individual chunk doesn't matter as long as the root computation completes in a timely fashion. In other words, Rayon does not provide any guarantees of fairness with regards to how each task gets scheduled.
On the other hand, tokio-threadpool is a general purpose scheduler and
attempts to schedule each task fairly. This is the ideal behavior when
scheduling a set of unrelated tasks.
Why not futures-cpupool?
It's 10x slower.
Examples
extern crate tokio_threadpool;
extern crate futures;
use tokio_threadpool::*;
use futures::*;
use futures::sync::oneshot;
pub fn main() {
let (tx, _pool) = ThreadPool::new();
let res = oneshot::spawn(future::lazy(|| {
println!("Running on the pool");
Ok::<_, ()>("complete")
}), &tx);
println!("Result: {:?}", res.wait());
}
