Detailed Description

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

CudaMutSpan is a non-owning reference to a continuous array of objects in CUDA storage which can be mutated through the span.

The region from which CudaMutSpan has been initialised needs to live throughout the span's lifetime. It is not possible to extend or shrink the region, but each element in it can be modified through the span.

CudaMutSpans can be created either using a 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 random access iterators ‘begin’ and ‘end’.

Template Parameters

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