Allows returning essentially arbitrary types by wrapping them into a PyResult. This is done with a conversion trait that specializes for PyResult.
This allows using generated code from crates that do not directly depend on pyo3. E.g.: ```rust extern crate my_pyo3_wrapper; use my_pyo3_wrapper::pyo3; #[py::modinit(rust2py)] fn init_mod(py: Python, m: &PyModule) -> PyResult<()> { // ... Ok(()) }
This makes the code generatioin reusable from third party crates.
