Struct DeviceView 

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

Non-owning immutable view over CUDA-accessible device memory.

This type is Copy because it models a shared immutable borrow: duplicating the view duplicates only the pointer/length pair and does not create or free device memory. The lifetime ties the view to the allocation or owner that created it, but CUDA kernels may still observe mutations performed through other aliases according to CUDA stream ordering.

Implementations

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

pub const unsafe fn from_raw_parts(ptr: *const T, length: usize) -> Self

Creates a borrowed immutable device view from a raw pointer and length.

Safety

ptr must be valid for length contiguous elements of T for the returned lifetime. If length is zero, ptr may be null; the stored view pointer is normalized to NonNull::dangling() because safe borrowed views should not expose null unless a vendor API explicitly requires it. The memory must remain alive and CUDA-accessible while the view is used.
