rayon-macro crate rayon-macro documentation minimum rustc 1.45 build status

The rayon-macro crate provides procedural macros to make it easier to transform serial code into rayon-enabled parallel code. For example, the parallel! macro can be used like this:

use rayon_macro::parallel;

parallel!(for i in 0..10 {
    println!("iteration {}", i);

It will be expanded to something like this:

(0..10).into_par_iter().for_each(|i| {
    println!("iteration {}", i);

Control-flow expressions in the body will also be transformed as needed.

This crate currently requires rustc 1.45.0 or greater.
