Struct PyMemoryView

pub struct PyMemoryView { /* private fields */ }

Implementations

impl PyMemoryView

pub fn from_object(obj: &PyObject, vm: &VirtualMachine) -> PyResult<Self>

this should be the main entrance to create the memoryview to avoid the chained memoryview

pub fn from_buffer(buffer: PyBuffer, vm: &VirtualMachine) -> PyResult<Self>

don’t use this function to create the memoryview if the buffer is exporting via another memoryview, use PyMemoryView::new_view() or PyMemoryView::from_object to reduce the chain

pub fn from_buffer_range( buffer: PyBuffer, range: Range<usize>, vm: &VirtualMachine, ) -> PyResult<Self>

don’t use this function to create the memeoryview if the buffer is exporting via another memoryview, use PyMemoryView::new_view() or PyMemoryView::from_object to reduce the chain

pub fn new_view(&self) -> Self

this should be the only way to create a memoryview from another memoryview

pub fn to_contiguous(&self, vm: &VirtualMachine) -> PyBuffer

clone data from memoryview keep the shape, convert to contiguous

impl PyMemoryView

pub fn release(&self)
