Detailed Description

template<typename T>
class syten::Cuda::CudaConstSpan< T >

CudaConstSpan is a non-owning constant reference to a continuous array of objects in CUDA storage.

The region from which CudaConstSpan has been initialised needs to live throughout the span's lifetime. It is not possible to extend or shrink the region, nor is it possible to mutate the elements in the region.

CudaConstSpans can be created either using a constant reference to a suitable container with a value_type member typedef or a plain pointer/size pair.

Remarks

Functionally, this is quite similar to a pair of constant random access iterators ‘begin’ and ‘end’.

Template Parameters

T	the type of the objects in the region of memory.
