Struct buf_rand::BufRand

pub struct BufRand<R: RngCore> { /* fields omitted */ }

used to generate random booleans using a bit buffer

Implementations

impl<R: RngCore> BufRand<R>

pub fn new(rand: R) -> Self

create a new BufRand which generates random booleans using the supplied rng

pub fn next_bool(&mut self) -> bool

returns a random boolean from the buffer of this BufRand

use buf_rand::BufRand;
 
let mut rand = BufRand::new(Box::new(rand::thread_rng()));
rand.next_bool();

pub fn rand_char_case(&mut self, c: &char) -> String

randomizes the capitalization of a char this returns a String since some chars may result in multiple when the case is changed such as this

//example of character turning into multiple
assert_eq!('ß'.to_uppercase().to_string(), "SS");
use buf_rand::BufRand;
 
let mut rand = BufRand::new(Box::new(rand::thread_rng()));
rand.rand_char_case(&'E');

pub fn rand_string_case(&mut self, s: &str) -> String

randomizes the capitalization of every character in the string

use buf_rand::BufRand;
 
let mut rand = BufRand::new(Box::new(rand::thread_rng()));
rand.rand_string_case("hello world!");

Trait Implementations

impl<R: RngCore> Deref for BufRand<R>

type Target = R

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

allows borrowing the randomizer this BufRand uses

impl<R: RngCore> DerefMut for BufRand<R>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
