Crate of the Week

This week's Crate of the Week is rayon, which gives us par_iter()/par_iter_mut() functions that use an internal thread pool to easily parallelize data-parallel operations. There's also rayon::join(|| .., || ..) for Fork-Join-style tasks. Apart from the ease of use, it also performs very well, comparable to hand-optimized code.

Thanks to LilianMoraru for the suggestion.
