Struct pyo3::PySlice

pub struct PySlice(_);

Represents a Python slice.

Only c_long indeces supprted at the moment by PySlice object.

Methods

impl PySlice

fn new(py: Python, start: isize, stop: isize, step: isize) -> &PySlice

Construct a new slice with the given elements.

fn indices(&self, length: c_long) -> PyResult<PySliceIndices>

Retrieve the start, stop, and step indices from the slice object slice assuming a sequence of length length, and store the length of the slice in slicelength.

Trait Implementations

impl AsRef<PyObjectRef> for PySlice

fn as_ref(&self) -> &PyObjectRef

Performs the conversion.

impl PyObjectWithToken for PySlice

fn py(&self) -> Python

impl ToPyPointer for PySlice

fn as_ptr(&self) -> *mut PyObject

Gets the underlying FFI pointer, returns a borrowed pointer.

impl PartialEq for PySlice

fn eq(&self, o: &PySlice) -> 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 !=.

impl PyTypeInfo for PySlice

type Type = ()

const SIZE: usize

SIZE: usize = ::std::mem::size_of::<::ffi::PyObject>()

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

const OFFSET: isize

OFFSET: isize = 0

Type instance offset inside PyObject structure

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

Class doc string

const FLAGS: usize

FLAGS: usize = 0

Type flags (ie PY_TYPE_FLAG_GC, PY_TYPE_FLAG_WEAKREF)

fn is_exact_instance(ptr: *mut PyObject) -> bool

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

impl PyTypeObject for PySlice

fn init_type()

Initialize type object

fn type_object() -> Py<PyType>

Retrieves the type object for this Python object type.

fn create(py: Python) -> PyResult<PyRawObject> where
    Self: Sized + PyObjectAlloc<Self> + PyTypeInfo, 

Create PyRawObject which can be initialized with rust value

impl ToPyObject for PySlice

fn to_object(&self, py: Python) -> PyObject

Converts self into a Python object.

impl ToBorrowedObject for PySlice

fn with_borrowed_ptr<F, R>(&self, _py: Python, f: F) -> R where
    F: FnOnce(*mut PyObject) -> R, 

Converts self into a Python object and calls the specified closure on the native FFI pointer underlying the Python object.
