Implementations

impl<'py, T> NotRequired<T>

where for<'a> &'a T: IntoPyObject<'py>, T: IntoPyObject<'py>, Self: ToOwned<Owned = Self>,

pub fn into_py_with( f: impl FnOnce(Python<'py>) -> PyResult<Bound<'py, PyAny>>, ) -> impl FnOnce(Cow<'_, Self>, Python<'py>) -> PyResult<Bound<'py, PyAny>>

See: https://pyo3.rs/v0.25.1/conversions/traits.html#deriveintopyobjectderiveintopyobjectref-field-attributes

You should always specify the type T like NotRequired::::into_py_with when using these methods, otherwise you may encounter a recursive IntoPyObject error.

pub fn into_py_with_none( slf: Cow<'_, Self>, py: Python<'py>, ) -> PyResult<Bound<'py, PyAny>>

pub fn into_py_with_default( slf: Cow<'_, Self>, py: Python<'py>, ) -> PyResult<Bound<'py, PyAny>>

where T: Default,

pub fn into_py_with_err( slf: Cow<'_, Self>, py: Python<'py>, ) -> PyResult<Bound<'py, PyAny>>
