rayon = "1.10.0"

• basic rayon usage

• Rayon is a data parallelism library for Rust that allows you to easily convert sequential computations into parallel ones.
• In this example, Rayon is used to perform a parallel sum of an array of integers

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

• The rayon::prelude::* is imported to access the parallel iterator methods like par_iter, which converts a regular iterator to a parallel iterator.

fn main() {
	let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
	let sum: i32 = arr.par_iter().sum();
	println!("Sum of array: {}", sum);
}

• sum() method is automatically executed in parallel across multiple threads available on the system.
• This results in a performance improvement, especially for larger data sets or more computationally intensive operations.
• By using Rayon, Rust programs can leverage modern multi-core processors efficiently and effortlessly without needing to manage threads and synchronization explicitly
