Struct cpython::PyTuple

pub struct PyTuple(_);

Represents a Python tuple object.

Methods

impl PyTuple

fn new(py: Python, elements: &[PyObject]) -> PyTuple

Construct a new tuple with the given elements.

fn empty(py: Python) -> PyTuple

Retrieves the empty tuple.

fn len(&self, _py: Python) -> usize

Gets the length of the tuple.

fn get_item(&self, py: Python, index: usize) -> PyObject

Gets the item at the specified index.

Panics if the index is out of range.

fn as_slice<'a>(&'a self, py: Python) -> &'a [PyObject]

fn iter(&self, py: Python) -> Iter<PyObject>

Trait Implementations

impl ToPyObject for PyTuple

Identity conversion: allows using existing PyObject instances where T: ToPyObject is expected.

type ObjectType = PyTuple

fn to_py_object(&self, py: Python) -> PyTuple

Converts self into a Python object.

fn into_py_object(self, _py: Python) -> PyTuple

Converts self into a Python object.

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.

impl<'source> FromPyObject<'source> for PyTuple

fn extract(py: Python, obj: &'source PyObject) -> PyResult<PyTuple>

Extracts Self from the source PyObject.

impl<'source> FromPyObject<'source> for &'source PyTuple

fn extract(py: Python, obj: &'source PyObject) -> PyResult<&'source PyTuple>

Extracts Self from the source PyObject.

impl PythonObject for PyTuple

fn as_object(&self) -> &PyObject

Casts the Python object to PyObject.

fn into_object(self) -> PyObject

Casts the Python object to PyObject.

unsafe fn unchecked_downcast_from(obj: PyObject) -> Self

Unchecked downcast from PyObject to Self. Undefined behavior if the input object does not have the expected type.

unsafe fn unchecked_downcast_borrow_from<'a>(obj: &'a PyObject) -> &'a Self

Unchecked downcast from PyObject to Self. Undefined behavior if the input object does not have the expected type.

impl PythonObjectWithCheckedDowncast for PyTuple

fn downcast_from<'p>(
    py: Python<'p>,
    obj: PyObject
) -> Result<PyTuple, PythonObjectDowncastError<'p>>

Cast from PyObject to a concrete Python object type.

fn downcast_borrow_from<'a, 'p>(
    py: Python<'p>,
    obj: &'a PyObject
) -> Result<&'a PyTuple, PythonObjectDowncastError<'p>>

Cast from PyObject to a concrete Python object type.

impl PythonObjectWithTypeObject for PyTuple

fn type_object(py: Python) -> PyType

Retrieves the type object for this Python object type.
