Struct board_game_geom::Rotation

pub struct Rotation(_, _, _, _);

A 2x2 rotation matrix.

Rotation(yy, yx, xy, xx) * Move(y, x) == Move(yy*y + yx*x, xy*y + xx*x)

Trait Implementations

impl Hash for Rotation

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl PartialEq for Rotation

fn eq(&self, __arg_0: &Rotation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Rotation) -> bool

This method tests for !=.

impl Eq for Rotation

impl Debug for Rotation

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Copy for Rotation

impl Clone for Rotation

fn clone(&self) -> Rotation

Returns a copy of the value.

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