Ranges Library

See the documentation of the standard headers <iterator> and <ranges>

Header	Content	Availability
<cuda/std/iterator>	Iterator related concepts and machinery such as `cuda::std::forward_iterator`	CCCL 2.3.0 / CUDA 12.4
<cuda/std/ranges>	Range related concepts and machinery such as `cuda::std::ranges::forward_range` and `cuda::std::ranges::subrange`	CCCL 2.4.0 / CUDA 12.5

Extensions

All library features are available from C++17 onwards. The concepts can be used like type traits prior to C++20.

template<cuda::std::contiguos_range Range>
void do_something_with_ranges_in_cpp20(Range&& range) {...}

template<class Range, cuda::std::enable_if_t<cuda::std::contiguos_range<Range>, int> = 0>
void do_something_with_ranges_in_cpp17(Range&& range) {...}

Restrictions

Subsumption does not work prior to C++20
Subsumption is only partially implemented in the compiler until nvcc 12.4

Omissions

Range based algorithms have not been implemented
Views have not been implemented
