Rayon parallel sum from range

help
1

A small question about Rayon. If I have code similar to:

(1 .. 100).map(|x| x * x).sum()

I'd like to compute it in parallel, something like:

(1 .. 100).par_iter().map(|x| x * x).sum()

Do you know what's the correct Rayon usage syntax?

This should work:

use rayon::par_iter::{IntoParallelIterator, ParallelIterator};

(1 .. 100).into_par_iter().map(|x| x * x).sum()
