[−][src]Struct pyo3::types::PyByteArray
Represents a Python bytearray
.
Methods
impl PyByteArray
[src]
pub fn new<'p>(py: Python<'p>, src: &[u8]) -> &'p PyByteArray
[src]
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,
[src]
I: ToPyPointer,
Creates a new Python bytearray object from other PyObject, that implements the buffer protocol.
pub fn len(&self) -> usize
[src]
Gets the length of the bytearray.
pub fn is_empty(&self) -> bool
[src]
Check if bytearray is empty.
pub fn data(&self) -> &[u8]
[src]
Gets the Python bytearray data as byte slice.
pub fn resize(&self, len: usize) -> PyResult<()>
[src]
Resize bytearray object.

impl PyObjectAlloc for PyByteArray
[src]
unsafe fn alloc(_py: Python) -> PyResult<*mut PyObject>
[src]
unsafe fn dealloc(py: Python, obj: *mut PyObject)
[src]
Calls the rust destructor for the object and frees the memory (usually by calling ptr->ob_type->tp_free). This function is used as tp_dealloc implementation. Read more
