Struct NonZeroHex8 

pub struct NonZeroHex8(/* private fields */);

8-bit unsigned nonzero hexadecimal numbers.

use hex_wrapper::NonZeroHex8;

// from random value
let rand = NonZeroHex8::rand();
let inner = rand.get();
assert_eq!(rand.to_string(), format!("{:x}", inner));

// from given value
let given = NonZeroHex8::new(0xa3).unwrap();
assert_eq!(given.to_string(), String::from("a3"));

// from string
let from_str = "a3".parse::<NonZeroHex8>();
assert_eq!(from_str.unwrap(), NonZeroHex8::new(0xa3).unwrap());

Implementations

impl NonZeroHex8

pub fn new(n: u8) -> Option<Self>

pub unsafe fn new_unchecked(n: u8) -> Self

Safety

The value must not be zero.

impl NonZeroHex8

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) -> NonZero<u8>

Gets the interior value.

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

Borrows the interior value.

pub const fn get_ref_mut(&mut self) -> &mut NonZero<u8>

Gets the mutable reference to the interior value.

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

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