In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:
- Separate big codebases into multiple repositories.

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:
ctypes
I typically wrap all these commands into a shell script that I can reuse, but here they are in steps.
Please read through all the instructions before actually performing the commands, just to avoid any surprises
