Crate pyenum_derive 

#[derive(PyEnum)] procedural macro.

Parsing, validation, and codegen live in the submodules and are wired together by derive_pyenum. The generated code only names items re-exported from pyenum::__private, so the output is stable across internal refactors of the runtime crate.

See the pyenum crate docs for usage, worked examples, and scope.
