Struct PySlice 

pub struct PySlice { /* private fields */ }

A wrapper around ndslice::Slice to expose it to python. It is a compact representation of indices into the flat representation of an n-dimensional array. Given an offset, sizes of each dimension, and strides for each dimension, Slice can compute indices into the flat array.

Trait Implementations

impl PyClassImpl for PySlice

const IS_BASETYPE: bool = false

#[pyclass(subclass)]

const IS_SUBCLASS: bool = false

#[pyclass(extends=…)]

const RAW_DOC: &'static CStr = /// A wrapper around [ndslice::Slice] to expose it to python. /// It is a compact representation of indices into the flat /// representation of an n-dimensional array. Given an offset, sizes of /// each dimension, and strides for each dimension, Slice can compute /// indices into the flat array.

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<PySlice>

This handles following two situations:

type Inventory = Pyo3MethodsInventoryForPySlice

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

fn dict_offset() -> Option<isize>

fn weaklist_offset() -> Option<isize>

impl PyClassNewTextSignature for PySlice

const TEXT_SIGNATURE: &'static str = "(*, offset, sizes, strides)"

impl PyClass__eq__SlotFragment<PySlice> for PyClassImplCollector<PySlice>

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

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

Returns the safe abstraction over the type object.

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

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

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

Checks if object is an instance of this type.
