Implementations§

source§

impl PyList

source

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

Construct a new list with the given elements.

source

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

Gets the length of the list.

source

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.

source

pub fn set_item(&self, _py: Python<'_>, index: usize, item: PyObject)

Sets the item at the specified index.

Panics if the index is out of range.

source

pub fn insert(&self, _py: Python<'_>, index: usize, item: PyObject)

Inserts an item at the specified index.

Panics if the index is out of range.

source

pub fn append(&self, _py: Python<'_>, item: PyObject)

Appends an item to the end of the list

source

pub fn iter<'a, 'p>(&'a self, py: Python<'p>) -> PyListIterator<'a, 'p>

Trait Implementations§

source§

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

source§

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

Extracts Self from the source PyObject.
source§

impl<'s> FromPyObject<'s> for PyList

source§

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

source§

impl PythonObject for PyList

source§

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.

source§

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.

source§

fn as_object(&self) -> &PyObject

Casts the Python object to PyObject.
source§

fn into_object(self) -> PyObject

Casts the Python object to PyObject.
source§

impl PythonObjectWithCheckedDowncast for PyList

source§

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

Cast from PyObject to a concrete Python object type.
source§

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

Cast from PyObject to a concrete Python object type.
source§

impl PythonObjectWithTypeObject for PyList

source§

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

Retrieves the type object for this Python object type.
source§

impl ToPyObject for PyList

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

§

type ObjectType = PyList

source§
