Function python_oxidized_importer::PyInit_oxidized_importer

#[no_mangle]
pub extern "C" fn PyInit_oxidized_importer() -> *mut PyObject

Module initialization function.

This creates the Python module object.

We don’t use the macros in the pyo3 crate because they are somewhat opinionated about how things should work. e.g. they call PyEval_InitThreads(), which is undesired. We want total control.
