## What it is
rust-cpython is a Rust library providing bindings to the Python interpreter, enabling Rust code to call Python and Rust extension modules to be exposed as Python libraries. It is no longer actively maintained, with PyO3 recommended as its successor.

## Use cases
- embed the python interpreter in a rust application
- write python extension modules in rust
- call python code from rust
- expose rust functions to python
- interoperate between rust and python

## When to choose
- maintaining an existing codebase already built on rust-cpython
- you need python 2.7 support which pyo3 dropped

## When to avoid
- starting a new rust-python binding project
- you want an actively maintained library
- you need support for python 3.13 or newer

## Facets
- artifact type: library
- maturity: abandoned
- function: sdk, parser
- domain: developer-tools, programming-languages, cross-platform
- platform: rust, python, cross-platform
- tags: python-bindings, ffi, extension-module, deprecated, pyo3-alternative
