pub fn payload_is<T: PyObjectPayload>(&self) -> bool

Force to return payload as T.

Safety

The actual payload type must be T.

pub fn dict(&self) -> Option<PyDictRef>

pub fn set_dict(&self, dict: PyDictRef) -> Result<(), PyDictRef>

Set the dict field. Returns Err(dict) if this object does not have a dict field in the first place.

pub fn payload_if_subclass<T: PyPayload>( &self, vm: &VirtualMachine ) -> Option<&T>

pub fn downcast_ref<T: PyObjectPayload>(&self) -> Option<&Py<T>>

pub fn downcast_ref_if_exact<T: PyObjectPayload + PyPayload>( &self, vm: &VirtualMachine ) -> Option<&Py<T>>

pub unsafe fn downcast_unchecked_ref<T: PyObjectPayload>(&self) -> &Py<T>

pub fn get_iter(&self, vm: &VirtualMachine) -> PyResult<PyIter>

Takes an object and returns an iterator for it. This is typically a new iterator but if the argument is an iterator, this returns itself.

Trait Implementations

impl AsRef<PyObject> for ArgMapping

fn as_ref(&self) -> &PyObject

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<PyObject> for ArgMapping

fn borrow(&self) -> &PyObject

Immutably borrows from an owned value.

impl Clone for ArgMapping

fn clone(&self) -> ArgMapping

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArgMapping

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for ArgMapping

type Target = PyObject

The resulting type after dereferencing.

fn deref(&self) -> &PyObject

fn from(value: ArgMapping) -> PyObjectRef

Converts to this type from the input type.

impl ToPyObject for ArgMapping
