Struct pyo3::PyByteArray

pub struct PyByteArray(_);

Represents a Python bytearray.

Methods

impl PyByteArray

pub fn new<'p>(py: Python<'p>, src: &[u8]) -> &'p PyByteArray

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

Panics if out of memory.

pub fn from<'p, I>(py: Python<'p>, src: &'p I) -> PyResult<&'p PyByteArray> where
    I: ToPyPointer, 

Creates a new Python bytearray object from other PyObject, that implements the buffer protocol.

pub fn len(&self) -> usize

Gets the length of the bytearray.

pub fn is_empty(&self) -> bool

Check if bytearray is empty.

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

Gets the Python bytearray data as byte slice.

pub fn resize(&self, len: usize) -> PyResult<()>

Resize bytearray object.
