Struct Digit

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

A digit that can be entered in a cell of a sudoku.

Implementations

impl Digit

pub fn as_set(self) -> Set<Self>

Returns a Set<Self> with the bit corresponding to this element set.

impl Digit

pub fn new(digit: u8) -> Self

Constructs a new Digit.

Panic

Panics, if the digit is not in the range of 1..=9.

pub fn new_checked(digit: u8) -> Option<Self>

Constructs a new Digit. Returns None, if the digit is not in the range of 1..=9.

pub fn all() -> impl Iterator<Item = Self>

Returns an iterator over all digits.

pub fn get(self) -> u8

Returns the digit contained within.

pub fn as_index(self) -> usize

Returns the number contained within as usize, offset by -1. Guarantees that the numbering starts from 0.

Trait Implementations

impl Clone for Digit

fn clone(&self) -> Digit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Digit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Digit

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Digit

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Digit

fn eq(&self, other: &Digit) -> 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.

impl PartialOrd for Digit

fn partial_cmp(&self, other: &Digit) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl SetElement for Digit

const ALL: u16 = 511u16

const NONE: u16 = 0u16

type Storage = u16

fn count_possibilities(set: Self::Storage) -> u32

fn as_set(self) -> Set<Self>
