read_aepx, read_aepx_with_limits and parse_any build the owned chunk tree element by element again, as before the .aepx index, instead of converting the index (which held the decoded buffer and the owned tree at the same time). Import keeps the index reader. The tests now compare the two production readers.

//! 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.
