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 fn get(self) -> u8

Gets the interior value.

pub 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.
