Crate pyenum_derive 

#[derive(PyEnum)] procedural macro.

This is the entry-point crate. Parsing, validation, and codegen live in the submodules and are wired together by derive_pyenum below. The generated code references only items re-exported from pyenum::__private so the output is feature-flag-free — the runtime crate’s compat module resolves those names per the active pyo3-0_XX feature.
