Struct Hex128 

pub struct Hex128(/* private fields */);

128-bit unsigned hexadecimal numbers.

use hex_wrapper::Hex128;

// from random value
let rand = Hex128::rand();
let inner = rand.get();
assert_eq!(rand.to_string(), format!("{:x}", inner));

// from given value
let given = Hex128::new(0xa3);
assert_eq!(given.to_string(), String::from("a3"));

// from string
let from_str = "a3".parse::<Hex128>();

Implementations

impl Hex128

pub fn new(n: u128) -> Self

impl Hex128

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) -> u128

Gets the interior value.

pub const fn get_ref(&self) -> &u128

Borrows the interior value.

pub const fn get_ref_mut(&mut self) -> &mut u128

Gets the mutable reference to the interior value.

pub const fn from(n: u128) -> Self

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

fn eq(&self, other: &Hex128) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
