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:

```rust
use rayon_macro::parallel;

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

It will be expanded to something like this:

```rust
(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.
