Module node 

Runtime animation nodes and their interpreters. Runtime animation nodes and their interpreters.

This is the closed core of the animation tree: NodeContent is the runtime vocabulary (sequence, stack, leaf, static, audio), AnimNode wraps it with the timing shell, and all structural traversals — visual evaluation, seal-time audio baking, and preview introspection — live here.

Authoring sugar (AnimSequence, AnimStack, AnimLagged) is layered on top in crate::animation::compose; user leaf protocols live in crate::animation::eval.

Structs

AnimNode

A single runtime animation node: one closed NodeContent plus everything every kind shares — the subtree, the content axis, and the timing shell (window, rate, enable) in this node’s parent’s coordinates.

AnimationInfo

Hierarchical runtime animation information used by preview tooling.

MixAff 🔒

An affine map from global seconds to content seconds: t = a + b·x.

Enums

AnimationInfoKind

Runtime animation content category used by preview tooling.

NodeContent 🔒

What a runtime node IS — the closed vocabulary of the tree.

Residual 🔒

The non-linear remainder of the audio plane, as a compact tree.

ResidualLink 🔒

Construction-time residual: paths keyed by node identity, so shared prefixes merge soundly; ResidualLink::compact then flattens it into the walked form.

Functions

bake_audio 🔒

Bake the tree’s whole audio plane over [0, total_secs] into one interleaved stereo buffer at sample_rate.

eval_sequence 🔒

Sequence evaluation: the LAST child containing the content time runs (children placed with .at() inside a sequence may overlap; the later one wins — this exclusivity is what makes a sequence more than sugar for a stack of placements).

eval_stack 🔒

Stack evaluation: EVERY child containing the content time runs, outputs sum.

static_cell 🔒

Build a static cell replaying already-sampled items over time_range.
