msrtc-rans-python
Python extension module for msrtc_rans (via PyO3).
This crate provides Python bindings for the msrtc_rans entropy coder. Built with PyO3, it exposes the _msrtc_rans native module backed by maturin mixed project builds.
Status — Phase 6 Complete ✅
| Component | Status |
|---|---|
| PyO3 module structure | ✅ Full |
| Safe buffer handling | ✅ PyBuffer-based, no unsafe pointer casts |
| Persistent multipart streaming | ✅ RansEncoderStream holds persistent encoder state |
| Python bindings | ✅ Full API (EntropyEncoder, EntropyDecoder, streams) |
| Type stubs | ✅ _msrtc_rans.pyi |
| Wheel builds | ✅ maturin mixed project layout |
| Upstream tests pass | ✅ All 7 upstream Python tests pass |
The Python extension is fully functional. All 7 upstream msrtc_rans Python tests pass against the Rust implementation. The msrtc.rans package (EntropyEncoder, EntropyDecoder, RansEncoderStream, RansDecoderStream) provides the complete Python API.
