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.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Alphabetic

fn default() -> Alphabetic

Returns the “default value” for a type.

impl Distribution<u8> for Alphabetic

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> u8

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> Iter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> Map<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Map sampled values to type S

impl SampleString for Alphabetic

Available on crate feature alloc only.

fn append_string<R: Rng + ?Sized>( &self, rng: &mut R, string: &mut String, len: usize, )

Append len random chars to string

fn sample_string<R: Rng + ?Sized>(&self, rng: &mut R, len: usize) -> String

Generate a String of len random chars

impl Copy for Alphabetic

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
