Struct cpython::PyTuple

pub struct PyTuple(/* private fields */);

Represents a Python tuple object.

Implementations

impl PyTuple

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

Construct a new tuple with the given elements.

pub fn empty(py: Python<'_>) -> PyTuple

Retrieves the empty tuple.

pub fn len(&self, _py: Python<'_>) -> usize

Gets the length of the tuple.

pub fn get_item(&self, py: Python<'_>, index: usize) -> PyObject

Gets the item at the specified index.

Panics if the index is out of range.

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

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

Trait Implementations

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

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

Extracts Self from the source PyObject.

impl<'s> FromPyObject<'s> for PyTuple

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

Extracts Self from the source PyObject.

impl PythonObject for PyTuple

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.

fn as_object(&self) -> &PyObject

Casts the Python object to PyObject.

fn into_object(self) -> PyObject

Casts the Python object to PyObject.

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.

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.
