Struct hex_wrapper::Hex8

pub struct Hex8(_);

8-bit unsigned hexadecimal numbers.

use hex_wrapper::Hex8;

// from random value
let rand = Hex8::rand();
let inner = rand.get();
assert_eq!(rand.to_string(), format!("{:x}", inner));

// from given value
let given = Hex8::new(0xa3);

// from string
let from_str = "a3".parse::<Hex8>();

Implementations

impl Hex8

pub fn new(n: u8) -> Self

Creates a null hex (i.e., 0).

impl Hex8

pub fn rand() -> Self

Creates a random hex. This is equivalent to Self::with_rng(rand::thread_rng()).

pub fn with_rng(rng: &mut impl Rng) -> Self

Creates a random hex.

pub const fn get(self) -> u8

Gets the interior value.

pub const fn get_ref(&self) -> &u8

Borrows the interior value.

pub fn get_ref_mut(&mut self) -> &mut u8

Gets the mutable reference to the interior value.

pub const fn from(n: u8) -> Self

The converse of Self::get(). This is same as the implementation of From.

impl FromStr for Hex8

type Err = ParseIntError

The associated error which can be returned from parsing.

impl Ord for Hex8

fn cmp(&self, other: &Hex8) -> Ordering

This method returns an Ordering between self and other.
