impl PyLens

pub(crate) unsafe fn __pymethod___and____( py: Python<'_>, _raw_slf: *mut PyObject, arg0: *mut PyObject, ) -> PyResult<*mut PyObject>

Trait Implementations

impl Clone for PyLens

fn clone(&self) -> PyLens

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DerefToPyAny for PyLens

impl IntoPy<Py<PyAny>> for PyLens

fn into_py(self, py: Python<'_>) -> PyObject

Performs the conversion.

impl PyClass for PyLens

type Frozen = True

Whether the pyclass is frozen.

impl PyClassImpl for PyLens

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const IS_MAPPING: bool = false

#[pyclass(mapping)]

const IS_SEQUENCE: bool = false

#[pyclass(sequence)]

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<PyLens>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::ImmutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.

fn items_iter() -> PyClassItemsIter

fn doc(py: Python<'_>) -> PyResult<&'static CStr>

Rendered class doc

fn lazy_type_object() -> &'static LazyTypeObject<Self>

fn dict_offset() -> Option<isize>

fn weaklist_offset() -> Option<isize>

impl PyClass__and__SlotFragment<PyLens> for PyClassImplCollector<PyLens>

unsafe fn __and__( self, py: Python<'_>, _raw_slf: *mut PyObject, arg0: *mut PyObject, ) -> PyResult<*mut PyObject>

Safety: _slf and _other must be valid non-null Python objects

impl PyClass__or__SlotFragment<PyLens> for PyClassImplCollector<PyLens>

unsafe fn __or__( self, py: Python<'_>, _raw_slf: *mut PyObject, arg0: *mut PyObject, ) -> PyResult<*mut PyObject>

Safety: _slf and _other must be valid non-null Python objects

type Holder = Option<PyRef<'py, PyLens>>

fn extract( obj: &'a Bound<'py, PyAny>, holder: &'a mut Self::Holder, ) -> PyResult<Self>

impl PyMethods<PyLens> for PyClassImplCollector<PyLens>

fn py_methods(self) -> &'static PyClassItems

impl PyTypeInfo for PyLens

const NAME: &'static str = "Lens"

Class name.

const MODULE: Option<&'static str>

Module name, if any.

fn type_object_raw(py: Python<'_>) -> *mut PyTypeObject

Returns the PyTypeObject instance for this type.

fn type_object_bound(py: Python<'_>) -> Bound<'_, PyType>

Returns the safe abstraction over the type object.

fn is_type_of_bound(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type or a subclass of this type.

fn is_exact_type_of_bound(object: &Bound<'_, PyAny>) -> bool

Checks if object is an instance of this type.
