Struct cpython::PyBytes

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

Represents a Python byte string. Corresponds to str in Python 2, and bytes in Python 3.

Implementations

impl PyBytes

pub fn new(py: Python<'_>, s: &[u8]) -> PyBytes

Creates a new Python byte string object. The byte string is initialized by copying the data from the &[u8].

Panics if out of memory.

pub fn data(&self, _py: Python<'_>) -> &[u8]

Gets the Python string data as byte slice.

Trait Implementations

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

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

Extracts Self from the source PyObject.

impl<'s> FromPyObject<'s> for PyBytes

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

Extracts Self from the source PyObject.

impl PythonObject for PyBytes

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 PyBytes

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

Cast from PyObject to a concrete Python object type.

impl PythonObjectWithTypeObject for PyBytes

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

Retrieves the type object for this Python object type.

impl ToPyObject for PyBytes

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

type ObjectType = PyBytes

fn to_py_object(&self, py: Python<'_>) -> PyBytes

Converts self into a Python object.

fn into_py_object(self, _py: Python<'_>) -> PyBytes

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.
