Crate pyo3_build_config[−][src]
Expand description
Configuration used by PyO3 for conditional support of varying Python versions.
This crate exposes two functions, use_pyo3_cfgs
and add_extension_module_link_args
,
which are intended to be called from build scripts to simplify building crates which depend on
PyO3.
It used internally by the PyO3 crate’s build script to apply the same configuration.
Structs
A list of python interpreter compile-time preprocessor defines that
we will pick up and pass to rustc via --cfg=py_sys_config={varname}
;
this allows using them conditional cfg attributes in the .rs files, so
Configuration needed by PyO3 to build for the correct Python implementation.
Enums
Functions
Adds linker arguments (for macOS) suitable for PyO3’s extension-module
feature.
Adds all the #[cfg]
flags to the current compilation.
