acorde-io

In-memory MusicXML, MIDI, ABC, and MuseScore I/O for acorde-core.

Default features are musicxml and midi. Optional features:

The default API includes parse_musicxml, parse_mxl, serialize_musicxml, parse_midi, serialize_midi, and serialize_midi_region. Parsers accept strings or byte slices and never touch the filesystem.

Each supported format also exposes *_with_report wrappers returning ImportReport or ExportReport<T>. Reports carry structured diagnostics with severity, source location, preserved value, and loss reason fields; an empty diagnostic list means no loss was detected by that API. Serialized reports include schema_version (currently 1); report readers should check this field before relying on future diagnostic fields. Reports written by older versions default to the current schema version when deserialized.

Parser and archive trust-boundary rules are documented in the security contract. Non-archive parser inputs use a 64 MiB baseline rejection limit; callers should enforce tighter budgets when their host resource envelope requires it. MIDI decoding also caps events at 500,000, and ABC token scanning caps each logical line at 1 MiB. MXL and MSCZ archives also reject a total declared uncompressed size above the archive budget before selecting or reading an entry, and reject duplicate or traversal-style entry names.

use acorde_io::{parse_musicxml, serialize_musicxml};

# fn main() -> Result<(), acorde_io::Error> {
# let xml = "<score-partwise version=\"3.1\"></score-partwise>";
let score = parse_musicxml(xml)?;
let output = serialize_musicxml(&score)?;
# let _ = output;
# Ok(())
# }
