Struct DeviceMemoryView 

pub struct DeviceMemoryView<T> { /* private fields */ }

A checked typed device span with a strong allocation owner. Subviews and reinterpretations preserve this same owner; none expose cudarc pointer traits.

Implementations

impl<T> DeviceMemoryView<T>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn stream(&self) -> &Arc<CudaStream>

pub fn device_ptr(&self) -> &u64

pub fn allocation_provenance(&self) -> Option<DeviceAllocationProvenance>

Preserve this view’s actual native allocation origin. A foreign owner supplies only its imported span, not proof of a complete allocation; never manufacture a native allocation identity for that case.

pub fn try_slice(&self, range: impl RangeBounds<usize>) -> Option<Self>

pub fn slice(&self, range: impl RangeBounds<usize>) -> Self

pub fn slice_mut(&mut self, range: impl RangeBounds<usize>) -> Self

pub unsafe fn cast<U>(&self) -> Option<DeviceMemoryView<U>>

Reinterpret the span without changing its allocation owner.

Safety

The initialized device bytes must have the representation required by U before any read through the returned view. Alignment and size are checked.
