#[repr(u8)]
pub enum Rotation {
    Up = 0,
    Right = 1,
    Down = 2,
    Left = 3,
}

Implementations

impl Rotation

pub const fn count(self) -> u8

pub const fn mirrored(self, horizontally: bool, vertically: bool) -> Self

mirror the directions.

pub fn mirror(&mut self, horizontally: bool, vertically: bool)

mirror in place

pub const fn rotated(self, clockwise: bool) -> Self

rotate the rotation

pub fn rotate(&mut self, clockwise: bool)

rotate the rotation in place

pub const fn rotated_180(self) -> Self

Trait Implementations

impl Clone for Rotation

fn clone(&self) -> Rotation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rotation

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

Formats the value using the given formatter.

impl From<Rotation> for u8

fn from(rot: Rotation) -> Self

Converts to this type from the input type.

impl From<u8> for Rotation

fn from(val: u8) -> Self

Converts to this type from the input type.

impl Hash for Rotation

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 Rotation

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