Enum Symmetry 

#[non_exhaustive]
pub enum Symmetry {
    VerticalMirror,
    HorizontalMirror,
    VerticalAndHorizontalMirror,
    DiagonalMirror,
    AntidiagonalMirror,
    BidiagonalMirror,
    QuarterRotation,
    HalfRotation,
    Dihedral,
    None,
}

Position symmetries for clues of generated sudokus

For use with functions like Sudoku::generate_with_symmetry.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

VerticalMirror

Mirror along the vertical axis through the center of the sudoku

HorizontalMirror

Mirror along the horizontal axis through the center of the sudoku

VerticalAndHorizontalMirror

Mirror along both vertical and horizontal axes through the center of the sudoku

DiagonalMirror

Mirror along the diagonal from the top left to the bottom right

AntidiagonalMirror

Mirror along the diagonal from the bottom left to the top right

BidiagonalMirror

Mirror along both diagonals

QuarterRotation

90° rotational symmetry (implies 180° and 270° symmetry)

HalfRotation

180° rotational symmetry

Dihedral

Mirror along both vertical and horizontal axes, both diagonals and 90° and 180° rotation

None

No symmetry

Trait Implementations

impl Clone for Symmetry

fn clone(&self) -> Symmetry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Symmetry

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

Formats the value using the given formatter.

impl Hash for Symmetry

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 PartialEq for Symmetry

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