Struct Transform2D 

pub struct Transform2D { /* private fields */ }

A 2D transform composed of position, rotation (in radians), and scale.

Implementations

impl Transform2D

Implements methods for Transform2D.

pub fn identity() -> Transform2D

Creates a new transform at the origin with no rotation and unit scale.

Returns

• Transform2D - The identity transform.

pub fn translate(&mut self, offset: Vector2D)

Translates the position by the given offset.

Arguments

• Vector2D - The translation offset.

pub fn rotate(&mut self, radians: f64)

Rotates by the given angle in radians.

Arguments

• f64 - The rotation delta in radians.

pub fn scale_by(&mut self, factors: Vector2D)

Scales by the given factors.

Arguments

• Vector2D - The scale factors.

pub fn apply_to_point(&self, point: Vector2D) -> Vector2D

Applies this transform to a local-space point, returning world-space coordinates.

Arguments

• Vector2D - The local-space point.

Returns

• Vector2D - The transformed world-space point.

Trait Implementations

impl Clone for Transform2D

fn clone(&self) -> Transform2D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Transform2D

impl Debug for Transform2D

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

Formats the value using the given formatter.

impl Default for Transform2D

Implements Default for Transform2D as the identity transform.

fn default() -> Transform2D

Returns the “default value” for a type.

impl PartialEq for Transform2D

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

fn partial_cmp(&self, other: &Transform2D) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
