Struct Possibility 

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

A position and value for a box inside of a Latin square puzzle.

Fields

row: usize

The row position of the box.

The values ranges from 0 to side_length - 1.

column: usize

The column position of the box.

The values ranges from 0 to side_length - 1.

value: usize

The value present inside of the box.

The values ranges from 1 to side_length.

Implementations

impl Possibility

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

Return an iterator over all possible Possibilitys for the given side_length.

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

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

pub fn satisfies(&self, constraint: &Constraint) -> bool

Return true if this Possibility satisfies the given Constraint.

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.
