Using Rust from Python
This chapter of the guide is dedicated to explaining how to wrap Rust code into Python objects.
PyO3 uses Rust's "procedural macros" to provide a powerful yet simple API to denote what Rust code should map into Python objects.
PyO3 can create three types of Python objects:
- Python modules, via the #[pymodule]macro
- Python functions, via the #[pyfunction]macro
- Python classes, via the #[pyclass]macro (plus#[pymethods]to define methods for those classes)
The following subchapters go through each of these in turn.
