A parallel FizzBuzz implementation with Rust. Requires Rayon ^0.6

fizzbuzz.rs

extern crate rayon;
use rayon::prelude::*;

fn fizzbuzz(i: i32) {
    match (i % 3 == 0, i % 5 == 0) {
         // Added showing instances where there is no valid divisor on /u/XANI_'s suggestion
        // I really like it, actually, because it lets you see how the parallel iterator has 
        // chunked up the problem. Very cool.
        (false, false) => {println!("{} ", i); },
        (true, true) => { println!("{}: FizzBuzz", i); },
        (true, false) => { println!("{}: Fizz", i); },
        (false, true) => { println!("{}: Buzz", i); }    
    }
}

fn main() {
    (1..75).into_par_iter().for_each(|n| { fizzbuzz(n);});
}
