Struct DeviceSliceMut 

pub struct DeviceSliceMut<'a, T: DeviceRepr> { /* private fields */ }

Mutable view into a range of a DeviceBuffer.

Implementations

impl<'a, T: DeviceRepr> DeviceSliceMut<'a, T>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn as_raw(&self) -> CUdeviceptr

pub unsafe fn from_raw_parts<'b>( ptr: CUdeviceptr, len: usize, ) -> DeviceSliceMut<'b, T>

Construct a DeviceSliceMut from a raw device pointer and element count.

Mutable counterpart of DeviceSlice::from_raw_parts.

Safety

All requirements of DeviceSlice::from_raw_parts apply, with the additional unique-access guarantee:

• No other reference (mutable or shared) may alias the pointed-to region for the lifetime 'b. This includes any DeviceSlice<'_, U> constructed from the same underlying storage, even at a different element type.

pub fn slice(&self, range: Range<usize>) -> DeviceSlice<'_, T>

Borrow a sub-range immutably. Panics on out-of-bounds / inverted.

pub fn slice_mut(&mut self, range: Range<usize>) -> DeviceSliceMut<'_, T>

Borrow a sub-range mutably.

pub fn copy_from_host_async(&self, src: &[T], stream: &Stream) -> Result<()>

Asynchronous H2D copy on stream. Mirrors DeviceBuffer::copy_from_host_async for slice views — useful when the destination is a sub-range of a larger device buffer (e.g. packing CUTLASS grouped-GEMM metadata into a caller-supplied workspace).
