Struct Alphabetic

pub struct Alphabetic;

Sample a u8, uniformly distributed over letters: a-z and A-Z.

Example

You’re able to generate random Alphabetic characters via mapping or via the SampleString::sample_string method like so:

use rand::Rng;
use rand::distr::{Alphabetic, SampleString};

// Manual mapping
let mut rng = rand::rng();
let chars: String = (0..7).map(|_| rng.sample(Alphabetic) as char).collect();
println!("Random chars: {}", chars);

// Using [`SampleString::sample_string`]
let string = Alphabetic.sample_string(&mut rand::rng(), 16);
println!("Random string: {}", string);

Passwords

Refer to Alphanumeric.
