Struct AnimSequence 

pub struct AnimSequence {
    animations: Vec<AnimationCell>,
    cursor_sec: f64,
}

Dynamic sequential animation container.

push erases each direct child’s Rust type while retaining its runtime composition hierarchy in this sequence’s local coordinates.

Fields

animations: Vec<AnimationCell>

cursor_sec: f64

Implementations

impl AnimSequence

pub fn new() -> Self

Create an empty sequence.

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

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

Append an animation at the current cursor and advance by its local extent.

pub fn extend(&mut self, sequence: AnimSequence) -> &mut Self

Append another sequence’s direct children at the current cursor.

pub fn forward(&mut self, secs: f64) -> &mut Self

Advance the cursor without adding an animation.

pub fn forward_to(&mut self, target_sec: f64) -> &mut Self

Advance the cursor to target_sec without adding an animation.

pub fn hold(&mut self, secs: f64) -> &mut Self

Advance the cursor while holding the state immediately before it.

pub fn hold_to(&mut self, target_sec: f64) -> &mut Self

Advance the cursor to target_sec while holding its current state.

pub fn cursor_sec(&self) -> f64

Current cursor position.

pub fn duration_secs(&self) -> f64

Current sequence duration.

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

Borrow the direct child animations in local sequence coordinates.

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

Consume this sequence into its direct child animations.

Trait Implementations

impl Animation for AnimSequence

fn build(self) -> AnimationCell

Lower this definition into its local runtime representation.

impl Default for AnimSequence

fn default() -> AnimSequence

Returns the “default value” for a type.

impl EvalDyn for AnimSequence

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 AnimSequence

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

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