Detailed Description

template<class ElementType>
requires std::is_trivially_copyable_v<ElementType>
struct uni20::cuda::CudaPointerAccessor< ElementType >

Accessor for a CUDA mdspan whose device pointer has been leased.

Indexed access applies the mapped offset and returns an element reference. The accessor must be evaluated only in an execution domain where the leased CUDA pointer is directly accessible. Persistent elements must be trivially copyable, including borrowed views.
