Building
Development Build
# Install maturin
pip install maturin
# Build and install in development mode
cd sgl-model-gateway/bindings/python
maturin develop --features vendored-openssl
Production Build
# Build wheel
cd sgl-model-gateway/bindings/python
maturin build --release --out dist --features vendored-openssl
# Install the built wheel
pip install dist/sglang_router-*.whl
Testing
# Run Python unit tests (after maturin develop)
cd sgl-model-gateway/bindings/python
pytest tests/
Configuration
- pyproject.toml: Defines package metadata, dependencies, and build configuration
- python-source: Set to
"src"indicating Python source uses the src layout - module-name:
sglang_router.sglang_router_rs- the Rust extension module name
Notes
- The Rust bindings source code is located in
src/lib.rs - The bindings have their own
Cargo.tomlin this directory - The main sglang-router library is located in
../../and is used as a dependency - The package includes both Python code and Rust extensions built with PyO3
- PyO3 types are prefixed with
Pyin Rust but exposed to Python without the prefix using thenameattribute
