+===========================
+
+The :ref:`ref-classes-python-setuptools3_rust` class enables building Python
+extensions implemented in Rust with `PyO3 <https://pyo3.rs/>`__, which allows
+to compile and distribute Python extensions written in Rust as easily
+as if they were written in C.
+
+This class inherits the :ref:`ref-classes-setuptools3` and
+:ref:`ref-classes-python_pyo3` classes.
