Trait Implementations

impl IntoPyObject for PyDAG

fn into_object(self, py: Python) -> PyObject

Converts self into a Python object. (Consumes self)

impl PyTypeInfo for PyDAG

type Type = PyDAG

Type of objects to store in PyObject struct

type BaseType = PyAny

Base class

const NAME: &'static str

Class name

const DESCRIPTION: &'static str

Class doc string

const FLAGS: usize

Type flags (ie PY_TYPE_FLAG_GC, PY_TYPE_FLAG_WEAKREF)

const SIZE: usize

Size of the rust PyObject structure (PyObject + rust structure)

const OFFSET: isize

Type instance offset inside PyObject structure

unsafe fn type_object() -> &'static mut PyTypeObject

PyTypeObject instance for this type, which might still need to be initialized

fn is_instance(object: &PyAny) -> bool

Check if *mut ffi::PyObject is instance of this type

fn is_exact_instance(object: &PyAny) -> bool

Check if *mut ffi::PyObject is exact instance of this type

impl PyMethodsInventoryDispatch for PyDAG

type InventoryType = PyDAGGeneratedPyo3Inventory

This allows us to get the inventory type when only the pyclass is in scope

impl PyObjectAlloc for PyDAG

unsafe fn alloc(_py: Python) -> *mut PyObject

unsafe fn dealloc(py: Python, obj: *mut PyObject)

Calls the rust destructor for the object and frees the memory (usually by calling ptr->ob_type->tp_free). This function is used as tp_dealloc implementation.

unsafe fn drop(py: Python, obj: *mut PyObject)

Calls the rust destructor for the object.
