I'm a bit puzzled: I had a PyO3 module which I've now removed completely... the Rust module directory and files have been deleted and there is no reference to them in any Cargo.toml files, or anywhere.
And yet, when I run my Python script it is still able to import the old Rust module, and run the PyO3 function which was in there.
I've tried Cargo clean but this doesn't seem to remove it. Obviously that's a Cargo-specific command, whereas what I really need is a PyO3-specific "clean" method.
I want Python to complain when I go import my_old_rust_module that the module can't be found.
