Since the example was using rust, I'm guessing the [std::simd module](https://doc.rust-lang.org/std/simd/index.html https://doc.rust-lang.org/std/simd/index.htm

Since the example was using rust, I'm guessing the [std::simd module](https://doc.rust-lang.org/std/simd/index.html https://doc.rust-lang.org/std/simd/index.html), which is currently unstable but would be cool to see put to use here
