- Issues
- to_ubjson()/to_bjdata() with use_type=true and use_size=false aborts in debug builds and emits invalid output in release builds
- Ideas: exploring ways to reduce compilation time
- Idea: borrowed / zero-copy read-only view over a source buffer
- Idea: lossless number round-tripping (raw / arbitrary-precision number mode)
- Idea: canonical / deterministic serialization (RFC 8785 JCS)
- Idea: arena / PMR document mode (O(1) teardown, allocation-free destruction)
- Fix stack overflow in binary format parsers (CBOR/MessagePack/UBJSON/BSON)
- Speed up dump(): buffered output and SWAR string escaping
- Speed up binary writing: value-type output sink + byte-swap number encoding
- Speed up parsing of contiguous input: numbers, strings, and UTF-8 (with optional simdutf)
