Enum Symmetry 

pub enum Symmetry {
    None,
    Rotational180,
    Rotational90,
    MirrorVertical,
    MirrorHorizontal,
    MirrorDiagonal,
}

Represents the type of symmetry to apply during board generation.

Variants

None

No symmetry (clues placed randomly).

Rotational180

180-degree rotational (point) symmetry.

Rotational90

90-degree rotational symmetry.

MirrorVertical

Mirror symmetry across the vertical center line.

MirrorHorizontal

Mirror symmetry across the horizontal center line.

MirrorDiagonal

Mirror symmetry across the main diagonal (top-left to bottom-right).

Implementations

impl Symmetry

pub fn get_partners(&self, r: usize, c: usize) -> Vec<(usize, usize)>

Returns the symmetric partners for a given cell (r, c).

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 Default for Symmetry

fn default() -> Symmetry

Returns the “default value” for a type.

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.

impl Copy for Symmetry

impl Eq for Symmetry

impl StructuralPartialEq for Symmetry
