Trait Implementations

impl CanvasEncoding<String> for Transform2D

fn encode_canvas(&self, append_to: &mut String)

Encodes this item by appending it to the specified string

fn clone(&self) -> Transform2D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transform2D

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Transform2D

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<SpriteTransform> for Transform2D

fn from(sprite_transform: SpriteTransform) -> Transform2D

Performs the * operation.

impl Mul for Transform2D

type Output = Transform2D

The resulting type after applying the * operator.

fn mul(self, other: Transform2D) -> Transform2D

Performs the * operation.

impl PartialEq for Transform2D

fn eq(&self, other: &Transform2D) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
