Struct AnimationCell 

pub struct AnimationCell {
    inner: Box<dyn EvalDyn>,
    rate_func: fn(f64) -> f64,
    time_range: Range<f64>,
    enabled: bool,
    anim_name: &'static str,
    entered: bool,
}

A single runtime animation node in its parent’s time coordinates.

Fields

inner: Box<dyn EvalDyn>

rate_func: fn(f64) -> f64

time_range: Range<f64>

enabled: bool

anim_name: &'static str

entered: bool

Whether this cell’s inner state has been reset for the current run.

Implementations

impl AnimationCell

pub fn time_range(&self) -> Range<f64>

Global or parent-relative time range, depending on its containing plan.

pub fn duration_secs(&self) -> f64

Duration in seconds.

fn shift_by(&mut self, offset_sec: f64)

pub fn enabled(&self) -> bool

Whether this clip contributes a value.

pub fn anim_name(&self) -> &str

Concrete evaluator type name captured before erasure.

pub fn active_at(&self, sec: f64) -> bool

Whether the given scene time is inside this clip’s inclusive range.

fn local_time(&self, sec: f64, prev_sec: f64) -> SegmentTime

Compute the time context in this cell’s local coordinates.

pub(crate) fn reset_entered(&mut self)

Mark this clip as not yet entered (used by SceneEvaluator::seek).

pub(crate) fn sample_at_sec(&self, sec: f64, output: &mut Vec<DynItem>)

Sample this clip at a scene time (pure; no tick advancement).

pub(crate) fn step_at_sec(&mut self, sec: f64, prev_sec: f64)

Advance this clip’s inner state along the logic grid.

Resets the inner state on first activation (deterministic replay), then steps it with the rate-warped local delta. Functional leaves and containers without iterative content step as no-ops.

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

Append normalized evaluation results after applying this node’s rate function.

pub fn eval_alpha_dyn(&self, alpha: f64) -> Vec<DynItem>

Evaluate normalized progress into a flat collection of scene items.

pub fn eval_at_sec(&self, sec: f64) -> Option<Vec<DynItem>>

Evaluate at a time contained in this clip’s inclusive range.

fn contains_sec(&self, sec: f64, parent_duration: f64) -> bool

pub(crate) fn animation_info(&self) -> AnimationInfo
