Struct Possibility 

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

A position on the chess board.

Fields

row: usize

The row index, ranging from 0 to n - 1.

column: usize

The column index, ranging form 0 to n - 1.

Implementations

impl Possibility

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

Return an iterator over all positions on the chess board for a given side length.

pub fn leading_diagonal(self, side_length: usize) -> usize

Return the leading diagonal index for a given side length.

This value ranges from 0 to n - 2.

pub fn trailing_diagonal(self) -> usize

Return the trailing diagonal index.

The value ranges from 0 to n - 2.

pub fn satisfied_constraints( self, side_length: usize, ) -> impl Iterator<Item = Constraint>

Return an iterator over all 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 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.
