    pub opacity: f32,
    pub background_color: Option<Color>,
    pub border_color: Option<Color>,
    pub transform: Option<Transform>,
    pub scale: f32,

    pub motion: Option<ActiveMotion>,
    pub css_animation: Option<ActiveCssAnimation>,
}

Dynamic render state for a single node

Contains all properties that can change without requiring a tree rebuild. These properties are updated by animations or state machines.

Fields

opacity: f32

Current opacity (0.0 - 1.0)

background_color: Option<Color>

Current background color (animated)

border_color: Option<Color>

Current border color (animated)

transform: Option<Transform>

Current transform (animated)

scale: f32

Current scale (animated, applied to transform)

opacity_spring: Option<SpringId>

Spring ID for opacity animation

bg_color_springs: Option<[SpringId; 4]>

Spring IDs for color animation (r, g, b, a)

transform_springs: Option<[SpringId; 4]>

Spring IDs for transform (translate_x, translate_y, scale, rotate)

hovered: bool

Whether this node is currently hovered

focused: bool

Whether this node is currently focused

pressed: bool

Whether this node is currently pressed

motion: Option<ActiveMotion>

Active motion animation (enter/exit) for this node

css_animation: Option<ActiveCssAnimation>

Active CSS keyframe animation for this node

This is separate from motion because CSS animations can have multiple keyframes (not just enter/exit) and different lifecycle.

Implementations

impl NodeRenderState

pub fn new() -> NodeRenderState

Create a new node render state with default values

pub fn is_animating(&self) -> bool

Check if any properties are currently animating

pub fn has_active_motion(&self) -> bool

Check if this node has an active motion animation

pub fn start_css_animation(&mut self, animation: MultiKeyframeAnimation)

Start a CSS keyframe animation for this node

Replaces any existing CSS animation.

pub fn has_active_css_animation(&self) -> bool

Check if this node has an active CSS animation

pub fn tick_css_animation(&mut self, dt_ms: f32) -> Option<&KeyframeProperties>

Tick the CSS animation and get current properties

Returns Some with current properties if animation is active, None otherwise.

pub fn stop_css_animation(&mut self)

Stop and remove the CSS animation

pub fn css_animation_properties(&self) -> Option<&KeyframeProperties>

Get the current CSS animation properties (if any)

Trait Implementations

impl Clone for NodeRenderState

fn clone(&self) -> NodeRenderState

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

Performs copy-assignment from source.

impl Debug for NodeRenderState

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

impl Default for NodeRenderState

fn default() -> NodeRenderState
