Module impl_

Main implementation module included in both the pyo3-build-config library crate and its build script.

Structs

BuildFlags

A list of python interpreter compile-time preprocessor defines.

CrossCompileConfig

Configuration needed by PyO3 to cross-compile for a target platform.

CrossCompileEnvVars 🔒

PyO3-specific cross compile environment variable values

InterpreterConfig

Configuration needed by PyO3 to build for the correct Python implementation.

PythonVersion

Sysconfigdata

Parsed data from Python sysconfigdata file

Triple

An LLVM target “triple”. Historically such things had three fields, though they’ve added additional fields over time.

Functions

cargo_env_var

Gets an environment variable owned by cargo.

conda_env_interpreter 🔒

cross_compile_from_sysconfigdata 🔒

Find cross compilation information from sysconfigdata file

cross_compiling_from_cargo_env

Detect whether we are cross compiling from Cargo and PYO3_CROSS_* environment variables and return an assembled CrossCompileConfig if so.

cross_compiling_from_to

Detect whether we are cross compiling and return an assembled CrossCompileConfig if so.

default_abi3_config 🔒

Generates “default” interpreter configuration when compiling “abi3” extensions without a working Python interpreter.

default_cross_compile 🔒

Generates “default” cross compilation information for the target.

default_lib_name_for_target 🔒

default_lib_name_unix 🔒

default_lib_name_windows 🔒

ends_with 🔒

env_var

Gets an external environment variable, and registers the build script to rerun if the variable changes.

escape 🔒

find_all_sysconfigdata

Finds _sysconfigdata*.py files for detected Python interpreters.

find_interpreter

Attempts to locate a python interpreter.

find_sysconfigdata 🔒

Finds the sysconfigdata file when the target Python library directory is set.

get_abi3_version

Gets the minimum supported Python version from PyO3 abi3-py* features.

get_env_interpreter 🔒

get_host_interpreter 🔒

Locates and extracts the build host Python interpreter configuration.

have_python_interpreter 🔒

Checks if we should look for a Python interpreter installation to get the target interpreter configuration.

is_abi3 🔒

Checks if abi3 or any of the abi3-py3* features is enabled for the PyO3 crate.

is_cpython_lib_dir 🔒

is_extension_module

Checks if the extension-module feature is enabled for the PyO3 crate.

is_graalpy_lib_dir 🔒

is_linking_libpython

Checks if we need to link to libpython for the current build target.

is_linking_libpython_for_target 🔒

Checks if we need to link to libpython for the target.

is_pypy_lib_dir 🔒

load_cross_compile_config 🔒

Detects the cross compilation target interpreter configuration from all available sources (PyO3 environment variables, Python sysconfigdata, etc.).

make_cross_compile_config

Generates an interpreter config suitable for cross-compilation.

make_interpreter_config

Generates an interpreter config which will be hard-coded into the pyo3-build-config crate. Only used by pyo3-build-config build script.

parse_script_output 🔒

parse_sysconfigdata

Parse sysconfigdata file

require_libdir_for_target 🔒

Checks if we need to discover the Python library directory to link the extension module binary.

run_python_script 🔒

Run a python script using the specified interpreter binary.

run_python_script_with_envs 🔒

Run a python script using the specified interpreter binary with additional environment variables (e.g. PYTHONPATH) set.

search_lib_dir 🔒

recursive search for _sysconfigdata, returns all possibilities of sysconfigdata paths

starts_with 🔒

target_triple_from_env

Gets the compilation target triple from environment variables set by Cargo.
