The container's `Pard` is now the only decoder of parameter definitions: `EffectParam` delegates to it and the export's test reference reads its encoded table back through it (no big-endian readers of its own). The export stores a checkbox default as on/off, as the importer reads it. Inside a strongly connected component of candidate precomp links (a file with a precomp loop), the per-composition searches share one budget of link visits; past it, a layer that would need a search is refused and reported, which never lets a loop in. Below the budget the decisions are the old ones exactly.

//! After Effects project (`.aep`) container reader and writer.
|
|
//!
|
|
//! An `.aep` is a `RIFX` container (big-endian RIFF) with form type `Egg!`. This crate reads it
|
|
//! into a lossless chunk tree ([`AepFile`]) and writes it back byte for byte. The XML form of a
|
|
//! project (`.aepx`) is read into the same tree by [`read_aepx`]; [`parse_any`] picks the reader
|
|
//! by content. See
|
|
//! `docs/aep-format.md` for the observed format and how it was established (clean room: only
|
|
//! files we generated ourselves, one change per file).
|
|
//!
|
|
//! [`Project::new`] opens a typed, read-only view over the tree: items, compositions
|
|
//! ([`CompHeader`]), layers ([`LayerHeader`], [`Transform`], effects, masks, text documents,
|
|
//! markers), properties, keyframes and footage. Only fields whose layout was verified against the
|
|
//! values the test files were made with are decoded; every accessor returns `None` (or an empty
|
|
//! list) on damaged data instead of failing.
