Struct Possibility 

pub struct Possibility {
    pub row: usize,
    pub column: usize,
    pub square: usize,
    pub value: usize,
}

A position and value for a box inside of a Sudoku puzzle.

Fields

row: usize

The row position of the box.

The values ranges from 0 to n - 1, where n is the length of the Sudoku board.

column: usize

The column position of the box.

The values ranges from 0 to n - 1, where n is the length of the Sudoku board.

square: usize

The index of the subgrid.

The values ranges from 0 to n - 1, where n is the length of the Sudoku board. This field is redundant in identifying where the box is inside of the Sudoku board, however it is necessary to speed up checking which Constraints are satisfied by this Possibility.

value: usize

The value present inside of the box.

The values ranges from 1 to n, where n is the length of the Sudoku board.

Implementations

impl Possibility

pub fn from_latin(latin: Possibility, box_side_length: usize) -> Self

Convert a latin_square::Possibility to a sudoku::Possibility.

pub fn satisfied_constraints(self) -> impl Iterator<Item = Constraint>

Return an iterator over the Constraints that are satisfied by this Possibility.

Trait Implementations

impl Clone for Possibility

fn clone(&self) -> Possibility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Possibility

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

Formats the value using the given formatter.

impl From<Possibility> for Possibility

fn from(src: Possibility) -> Self

Converts to this type from the input type.

impl Hash for Possibility

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 Possibility

fn cmp(&self, other: &Possibility) -> 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 Possibility

fn eq(&self, other: &Possibility) -> 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 Possibility

fn partial_cmp(&self, other: &Possibility) -> 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.
