This is a small demo of how to create a library in Rust and call it from Python (both CPython and PyPy) using the CFFI instead of ctypes.
Based on http://harkablog.com/calling-rust-from-c-and-python.html (dead) which used ctypes
CFFI is nice because:
- Reads C declarations (parses headers)
- Works in both CPython and PyPy (included with PyPy)
- Lower call overhead than
ctypes
