What is the Rayon library in Rust?

Rayon is a data parallelism library for Rust that makes it easy to write concurrent programs. It allows you to easily parallelize operations on collections.

How do I use Rayon to parallelize a for loop?

You can use the par_iter() method on a collection to create a parallel iterator. For example: my_vec.par_iter().for_each(|x| { /* process x */ });.

Are there any performance benchmarks available for Rayon?

Yes, there are several benchmarks available in the Rayon documentation and on GitHub that compare its performance against other libraries.

Can I use Rayon with async code?

Rayon is designed for synchronous code, but you can use it alongside async code by managing the threads carefully. Just ensure that you don't block the async runtime.
