Crate pyo3_build_config

Configuration used by PyO3 for conditional support of varying Python versions.

This crate exposes functionality 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

• BuildFlags
  A list of python interpreter compile-time preprocessor defines.
• CrossCompileConfig
  Configuration needed by PyO3 to cross-compile for a target platform.
• InterpreterConfig
  Configuration needed by PyO3 to build for the correct Python implementation.
• PythonVersion
• Triple
  A target “triple”. Historically such things had three fields, though they’ve added additional fields over time.

Enums

• BuildFlag
• PythonImplementation

Functions

• add_extension_module_link_args
  Adds linker arguments suitable for PyO3’s extension-module feature.
• cross_compiling_from_to
  Detect whether we are cross compiling and return an assembled CrossCompileConfig if so.
• find_all_sysconfigdata
  Finds _sysconfigdata*.py files for detected Python interpreters.
• get
  Loads the configuration determined from the build environment.
• parse_sysconfigdata
  Parse sysconfigdata file
• use_pyo3_cfgs
  Adds all the #[cfg] flags to the current compilation.
