Struct rand::distributions::Alphanumeric

pub struct Alphanumeric;

Sample a char, uniformly distributed over ASCII letters and numbers: a-z, A-Z and 0-9.

Example

use std::iter;
use rand::{Rng, thread_rng};
use rand::distributions::Alphanumeric;
 
let mut rng = thread_rng();
let chars: String = iter::repeat(())
        .map(|()| rng.sample(Alphanumeric))
        .take(7)
        .collect();
println!("Random chars: {}", chars);
