Struct AnimStack 

pub struct AnimStack {
    animations: Vec<AnimationCell>,
    duration_secs: f64,
}

Dynamic overlay animation container.

Unlike AnimSequence, every pushed animation keeps its own local start time and the stack duration is the maximum child extent.

Fields

animations: Vec<AnimationCell>

duration_secs: f64

Implementations

impl AnimStack

pub fn new() -> Self

Create an empty dynamic stack.

fn eval_at_sec_into(&self, target_sec: f64, output: &mut Vec<DynItem>)

pub fn push<A: Animation + 'static>(&mut self, animation: A) -> &mut Self

Add an animation without advancing the other children.

pub fn extend(&mut self, stack: AnimStack) -> &mut Self

Add all direct child animations from another dynamic stack.

pub fn duration_secs(&self) -> f64

Current maximum child extent.

pub fn built_animations(&self) -> &[AnimationCell]

Borrow the direct child animations in local stack coordinates.

pub fn into_built_animations(self) -> Vec<AnimationCell>

Consume this stack into its direct child animations.

Trait Implementations

impl Animation for AnimStack

fn build(self) -> AnimationCell

Lower this definition into its local runtime representation.

impl Default for AnimStack

fn default() -> AnimStack

Returns the “default value” for a type.

impl EvalDyn for AnimStack

fn eval_alpha_dyn_into(&self, alpha: f64, output: &mut Vec<DynItem>)

fn step_dyn(&mut self, time: &SegmentTime)

Advance one logic step. No-op by default (functional segments and containers without iterative leaves step for free).

fn info_kind(&self) -> AnimationInfoKind

fn content_duration_secs(&self) -> f64

fn child_infos(&self) -> Vec<AnimationInfo>

fn sample_dyn(&self, time: &SegmentTime, output: &mut Vec<DynItem>)

Sample at a full time context. Default rides the pure alpha path for containers and functional leaves; iterative leaves override it via the blanket impl below.

fn reset_dyn(&mut self)

Reset the internal state. No-op by default.

impl Placeable for AnimStack

fn at(self, offset_sec: f64) -> At<Self>

Place this definition at an offset in its parent’s local time coordinates.
