Implementations

impl CrossCompileEnvVars

fn from_env() -> Self

Grabs the PyO3 cross-compile variables from the environment.

Registers the build script to rerun if any of the variables changes.

fn any(&self) -> bool

Checks if any of the variables is set.

fn parse_version(&self) -> Result<(Option<PythonVersion>, Option<String>)>

Parses PYO3_CROSS_PYTHON_VERSION environment variable value into PythonVersion and ABI flags.

fn parse_implementation(&self) -> Result<Option<PythonImplementation>>

Parses PYO3_CROSS_PYTHON_IMPLEMENTATION environment variable value into PythonImplementation.

fn lib_dir_path(&self) -> Result<Option<PathBuf>>

Converts the stored PYO3_CROSS_LIB_DIR variable value (if any) into a PathBuf instance.

Ensures that the path is a valid UTF-8 string.
