Crate rayon_cond

Experimental iterator wrapper that is conditionally parallel or serial, using Rayon's ParallelIterator or the standard Iterator respectively.

Usage

First add this crate to your Cargo.toml:

[dependencies]
rayon-cond = "0.1"

Then in your code, it may be used something like this:

extern crate rayon_cond;

use rayon_cond::CondIterator;

fn main() {
    let args: Vec<_> = std::env::args().collect();

    // Run in parallel if there are an even number of args
    let par = args.len() % 2 == 0;

    CondIterator::new(args, par).enumerate().for_each(|(i, arg)| {
        println!("arg {}: {:?}", i, arg);
    });
}
