Embedding python into a Rust Hello World

[lllama]

My aim is to embed python into a Rust app and have the Rust app manage its lifecycle. Ideally, I'd like the python interpreter to run in a separate process/thread and communicate back with the main rust program, and I'd like to include some of my custom python code. I'm assuming this is all possible.

With that in mind, I've used cargo new to create a new Hello World application, and I've added pyembed to my cargo.toml. But now I'm a little confused as to what the workflow should be. Should I be using cargo build, or pyoxidizer build to build the file?

Depends on how portable you want your binary to be.

If all you need is something that runs on the machine it was built on, cargo build with pyembed as a dependency can just work. If you want to distribute your application, you probably want to involve pyoxidizer to generate linkable build artifacts.

I attempted to document this at https://gregoryszorc.com/docs/pyoxidizer/0.22.0/pyoxidizer_rust_generic_embedding.html. You may want to have a look at the CI jobs that build the pyoxy executables, as those do everything you would need to do to build a binary that can be distributed.

Awesome! Thanks Greg!
