ffi
PyO3 exposes much of Python's C API through the ffi
module.
The C API is naturally unsafe and requires you to manage reference counts, errors and specific invariants yourself. Please refer to the C API Reference Manual and The Rustonomicon before using any function from that API.
Testing
Currently, #341 causes cargo test
to fail with weird linking errors when the extension-module
feature is activated. For now you can work around this by making the extension-module
feature optional and running the tests with cargo test --no-default-features
:
[dependencies.pyo3]
version = "0.8.1"
[features]
extension-module = ["pyo3/extension-module"]
default = ["extension-module"]
