Implementation of py_cc_toolchain rule.

NOTE: This is a beta-quality feature. APIs subject to change until https://github.com/bazel-contrib/rules\_python/issues/824 is considered done.

rule py_cc_toolchain(name, headers, python_version, libs=None)

A toolchain for a Python runtime’s C/C++ information (e.g. headers)

This rule carries information about the C/C++ side of a Python runtime, e.g. headers, shared libraries, etc.

This provides ToolchainInfo with the following attributes:

• py_cc_toolchain: PyCcToolchainInfo
• toolchain_label: Label only present when --visibilefortesting=Truefor internal testing. The rule’s label; this allows identifying what toolchain implmentation was selected for testing purposes.

Attributes:

• name – (Name)
  A unique name for this target.
  mandatory
• – (label)
  Target that provides the Python headers. Typically this is a cc_library target.

  Required providers: CcInfo
• python_version – (str)
  The Major.minor Python version, e.g. 3.11
  mandatory
• libs – (label) (default None)
