Struct Transform 

pub struct Transform {
    pub tx: f64,
    pub ty: f64,
    pub sx: f64,
    pub sy: f64,
    pub rotate_deg: f64,
    pub anchor_x: f64,
    pub anchor_y: f64,
}

A cheap per-node visual transform (§8.4 animation): translation, uniform/non-uniform scale, and rotation about a unit anchor (0.0..1.0 within the node’s bounds; default center). Distinct from the layout frame — animating a Transform never triggers relayout, so it is the vehicle for movement/scaling animation. Each backend composes it onto the node’s laid-out frame via its native transform channel (CALayer/GskTransform/RenderTransform/NODE_TRANSFORM/…).

Fields

tx: f64

ty: f64

sx: f64

sy: f64

rotate_deg: f64

anchor_x: f64

Anchor for scale/rotation as a unit fraction of the node’s bounds (0.5,0.5 = center).

anchor_y: f64

Implementations

impl Transform

pub const IDENTITY: Transform

pub const fn translate(tx: f64, ty: f64) -> Transform

pub const fn scale(sx: f64, sy: f64) -> Transform

pub const fn rotate(deg: f64) -> Transform

pub fn is_identity(&self) -> bool

Whether this transform has no visual effect — backends skip applying it.

Trait Implementations

impl Animatable for Transform

fn lerp(self, to: Transform, t: f64) -> Transform

impl Clone for Transform

fn clone(&self) -> Transform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transform

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

Formats the value using the given formatter.

impl Default for Transform

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Transform

fn eq(&self, other: &Transform) -> 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 Copy for Transform

impl StructuralPartialEq for Transform
