Struct TransformationMatrix 

pub struct TransformationMatrix(/* private fields */);

A matrix representing a unitary transformation.

Can represent rotations, reflections, or combinations of rotations/reflections.

Implementations

impl TransformationMatrix

pub fn identity() -> Self

The identity transformation.

Maps any point to itself.

pub fn rotate(&self, angle: Rotation) -> Self

A rotation matrix rotating by the given Rotation.

pub fn reflect_vert(&self) -> Self

A matrix representing a reflection across the x-axis.

pub fn inverse(&self) -> Self

The inverse of the transformation matrix.

Trait Implementations

impl Clone for TransformationMatrix

fn clone(&self) -> TransformationMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransformationMatrix

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

Formats the value using the given formatter.

impl Default for TransformationMatrix

fn default() -> Self

Returns the “default value” for a type.

impl Deref for TransformationMatrix

type Target = [[i8; 2]; 2]

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for TransformationMatrix

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'de> Deserialize<'de> for TransformationMatrix

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Rotation> for TransformationMatrix

fn from(value: Rotation) -> Self

Converts to this type from the input type.

impl Hash for TransformationMatrix

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 Mul<Point> for TransformationMatrix

type Output = Point

The resulting type after applying the * operator.

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

Performs the * operation.

impl Mul for TransformationMatrix

type Output = TransformationMatrix

The resulting type after applying the * operator.

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

Performs the * operation.

impl PartialEq for TransformationMatrix

fn eq(&self, other: &TransformationMatrix) -> 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 Serialize for TransformationMatrix

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
