Trait Implementations

impl Clone for Whence

fn clone(&self) -> Whence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Whence

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

Formats the value using the given formatter.

impl Hash for Whence

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoPy<Py<PyAny>> for Whence

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

Performs the conversion.

impl PartialEq for Whence

fn eq(&self, other: &Whence) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PyClass for Whence

type Frozen = True

Whether the pyclass is frozen.

impl PyClassImpl for Whence

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<Whence>

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__eq__SlotFragment<Whence> for PyClassImplCollector<Whence>

unsafe fn __eq__( 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__ne__SlotFragment<Whence> for PyClassImplCollector<Whence>

unsafe fn __ne__( 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<'a, 'py> PyFunctionArgument<'a, 'py> for &'a Whence

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

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

impl PyMethods<Whence> for PyClassImplCollector<Whence>

fn py_methods(self) -> &'static PyClassItems

impl PyTypeInfo for Whence

type AsRefTarget = PyCell<Whence>

Utility type to make Py::as_ref work.

const NAME: &'static str = "Whence"

Class name.

const MODULE: Option<&'static str> = ::core::option::Option::None

Module name, if any.

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

Returns the PyTypeObject instance for this type.

fn type_object(py: Python<'_>) -> &PyType

Returns the safe abstraction over the type object.

fn is_type_of(object: &PyAny) -> bool

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

fn is_exact_type_of(object: &PyAny) -> bool

Checks if object is an instance of this type.
