[−][src]Trait pyo3::type_object::PyTypeInfo
Python type information.
All Python native types(e.g., PyDict
) and #[pyclass]
structs implement this trait.
This trait is marked unsafe because:
- specifying the incorrect layout can lead to memory errors
- the return value of type_object must always point to the same PyTypeObject instance

Required methods

[−]
