impl PyMemoryView
Sourcepub fn from_object(obj: &PyObject, vm: &VirtualMachine) -> PyResult<Self>
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
Sourcepub fn from_buffer(buffer: PyBuffer, vm: &VirtualMachine) -> PyResult<Self>
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
Sourcepub fn from_buffer_range(
buffer: PyBuffer,
range: Range<usize>,
vm: &VirtualMachine,
) -> PyResult<Self>
pub fn from_buffer_range( buffer: PyBuffer, range: Range<usize>, 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
Sourcepub fn new_view(&self) -> Self
pub fn new_view(&self) -> Self
this should be the only way to create a memoryview from another memoryview
Sourcepub fn to_contiguous(&self, vm: &VirtualMachine) -> PyBuffer
pub fn to_contiguous(&self, vm: &VirtualMachine) -> PyBuffer
clone data from memoryview keep the shape, convert to contiguous

Source§const HAS_FREELIST: bool = false
const HAS_FREELIST: bool = false
Whether this type has a freelist. Types with freelists require
immediate (non-deferred) GC untracking during dealloc to prevent
race conditions when the object is reused.
Source§const MAX_FREELIST: usize = 0
const MAX_FREELIST: usize = 0
Maximum number of objects to keep in the freelist.
Source§unsafe fn freelist_push(_obj: *mut PyObject) -> bool
unsafe fn freelist_push(_obj: *mut PyObject) -> bool
Try to push a dead object onto this type’s freelist for reuse.
Returns true if the object was stored (caller must NOT free the memory).
Called before tp_clear, so the payload is still intact. Read more

unsafe fn freelist_pop(_payload: &Self) -> Option<NonNull<PyObject>>
Try to pop a pre-allocated object from this type’s freelist.
The returned pointer still has the old payload; the caller must
reinitialize
ref_count, gc_bits, and payload. Read morefn into_pyobject(self, vm: &VirtualMachine) -> PyObjectRefwhere
