Motion bindings for continuous animation driven by AnimatedValue

This struct holds references to animated values that are sampled every frame during rendering, enabling smooth continuous animations.

Fields

translate_x: Option<Arc<Mutex<AnimatedValue>>>

Animated X translation

translate_y: Option<Arc<Mutex<AnimatedValue>>>

Animated Y translation

scale: Option<Arc<Mutex<AnimatedValue>>>

Animated uniform scale

scale_x: Option<Arc<Mutex<AnimatedValue>>>

Animated X scale

scale_y: Option<Arc<Mutex<AnimatedValue>>>

Animated Y scale

rotation: Option<Arc<Mutex<AnimatedValue>>>

Animated rotation (degrees) - spring-based

rotation_timeline: Option<TimelineRotation>

Animated rotation (degrees) - timeline-based for continuous spin

opacity: Option<Arc<Mutex<AnimatedValue>>>

Animated opacity

Implementations

impl MotionBindings

pub fn is_empty(&self) -> bool

Check if any bindings are set

pub fn get_transform(&self) -> Option<Transform>

Get the current translation from animated values

Returns a translation transform for the tx/ty bindings. Scale and rotation should be queried separately for proper centered application.

pub fn get_scale(&self) -> Option<(f32, f32)>

Get the current scale values from animated bindings

Returns (scale_x, scale_y) if any scale is bound. The renderer should apply this centered around the element.

pub fn get_rotation(&self) -> Option<f32>

Get the current rotation from animated values (in degrees)

The renderer should apply this centered around the element. Checks timeline-based rotation first, then spring-based.

pub fn get_opacity(&self) -> Option<f32>

Get the current opacity from animated value

Trait Implementations

impl Clone for MotionBindings

fn clone(&self) -> MotionBindings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for MotionBindings

fn default() -> MotionBindings

Returns the “default value” for a type.
