Packaging a Python/Rust hybrid
Hello,
I am in the process of figuring out packaging of a Python/Rust hybrid
and have a few questions. Specifically, my work is on updating the
matrix-synapse package[0]. Synapse is originally a Python package, but
the developers started rewriting some critical parts in Rust and used
Pyo3 as glue. After a lot of experimentation, I hacked together a first
working copr build[1], but I don’t know how to get it into a clean shape
or how that even looks like exactly.
* Should I move the Rust parts into a subpackage? What are the
conventions then (e.g. for naming)?
* What is the best way to install a Rust-generated so-file as Python
module into the Python sitearch dir?
* Currently, I bypass python-setuptools-rust completely and went with
Fedora’s Rust macros. Is that the preferred path?
* Are there some useful macros/macro options I can utilize, and where
is manual work required instead?
Thank you
Kai
