parstream

Compute function over iterator in a streaming fashion using thread pool and preserving order of elements.

Example

rust let xs: &[u64] = &[100, 4, 3, 2, 1, 0, 1, 2, 3, 4, 5]; let mut ys = Vec::new(); let f = |x| x*x; parstream::run(xs, 4, |x| { std::thread::sleep(std::time::Duration::from_millis(*x)); f(x) }, |y| ys.push(y), ); assert_eq!(ys, xs.iter().map(f).collect::<Vec<_>>());
