Struct Rotation

pub struct Rotation<T> { /* private fields */ }

An 2D rotation that is representable using an integer matrix.

Implementations

impl<T> Rotation<T>

where T: Zero + Unity + Neg<Output = T>,

pub const IDENTITY: Self

The identity rotation.

pub const CW_90: Self

The rotation by 90° clockwise.

pub const CW_180: Self

The rotation by 180° clockwise or counter-clockwise.

pub const CW_270: Self

The rotation by 270° clockwise (or 90° counter-clockwise).

pub const fn new(matrix: [T; 4]) -> Self

Creates a new rotation from the given matrix.

pub fn random_cardinal_with(rng: &mut impl Rng) -> Self

Randomly one of the four cardinal rotations with the given rng.

pub fn random_cardinal() -> Self

Randomly one of the four cardinal rotations with the thread-local rng.

Trait Implementations

impl<T: Clone> Clone for Rotation<T>

fn clone(&self) -> Rotation<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Rotation<T>

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

Formats the value using the given formatter.

impl<T: Hash> Hash for Rotation<T>

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<T> Mul<Vec2<T>> for Rotation<T>

where T: Zero + Unity + Neg<Output = T> + Add<Output = T> + Mul<Output = T> + Copy,

type Output = Vec2<T>

The resulting type after applying the * operator.

fn mul(self, rhs: Vec2<T>) -> Vec2<T>

Performs the * operation.

impl<T> Mul for Rotation<T>

where T: Zero + Unity + Neg<Output = T> + Add<Output = T> + Mul<Output = T> + Copy,

type Output = Rotation<T>

The resulting type after applying the * operator.

fn mul(self, rhs: Self) -> Self

Performs the * operation.

impl<T: PartialEq> PartialEq for Rotation<T>

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