Struct cpython::PyBytes

pub struct PyBytes(_);

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

Methods

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.

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

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

Gets the Python string data as byte slice.

Trait Implementations

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.

impl<'source> FromPyObject<'source> for PyBytes

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

Extracts Self from the source PyObject.

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

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

Extracts Self from the source PyObject.

impl PythonObject for PyBytes

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.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

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 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.
