fix: exclude external_packages bindings from uniffi wheels#3013
external_packages bindings from uniffi wheels#3013Conversation
When `uniffi.toml` defines `external_packages` in `[bindings.python]`, the generated Python bindings for those external crates are now excluded from the wheel and `__init__.py`. Previously they were included, causing import failures since the external crate's cdylib is not bundled in the wheel. Fixes PyO3#2459
