Struct pyo3::PyBytes

pub struct PyBytes(_);

Represents a Python byte string.

Methods

impl PyBytes

fn new(_py: Python, s: &[u8]) -> Py<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.

unsafe fn from_ptr(_py: Python, ptr: *const u8, len: usize) -> Py<PyBytes>

Creates a new Python byte string object from raw pointer.

Panics if out of memory.

fn data(&self) -> &[u8]

Gets the Python string data as byte slice.

Trait Implementations

impl AsRef<PyObjectRef> for PyBytes

fn as_ref(&self) -> &PyObjectRef

Performs the conversion.

impl PyObjectWithToken for PyBytes

fn py(&self) -> Python

impl ToPyPointer for PyBytes

fn as_ptr(&self) -> *mut PyObject

Gets the underlying FFI pointer, returns a borrowed pointer.

impl PartialEq for PyBytes

fn eq(&self, o: &PyBytes) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PyTypeObject for PyBytes

fn init_type()

fn create(py: Python) -> PyResult<PyRawObject> where
    Self: Sized + PyObjectAlloc<Self> + PyTypeInfo, 

Create PyRawObject which can be initialized with rust value

impl ToPyObject for PyBytes

fn to_object(&self, py: Python) -> PyObject

Converts self into a Python object.

impl ToBorrowedObject for PyBytes

fn with_borrowed_ptr<F, R>(&self, _py: Python, f: F) -> R where
    F: FnOnce(*mut PyObject) -> R,
