Is there a more idiomatic way to initialize an array with random numbers than a for loop?

Question

Is there an idiomatic way of initialising arrays in Rust. I\'m creating an array of random numbers and was wondering if there is a more idiomatic way then just doing a for l

Answer 1

Various sized arrays can be directly randomly generated:

use rand; // 0.7.3

fn main() {
    let my_array: [u64; 8] = rand::random();
    println!("{:?}", my_array);
}

Currently, this only works for arrays of size from 0 to 32 (inclusive). Beyond that, you will want to see related questions:
