Deprecate and replace some Thrust iterator traits #3928

bernhardmgruber · 2025-02-24T14:16:03Z

This PR is similar to #3924, but for Thrust.

We add:

namespace thrust::detail {
template <typename It>
using it_value_t = typename ::cuda::std::iterator_traits<It>::value_type;

template <typename It>
using it_reference_t = typename ::cuda::std::iterator_traits<It>::reference;

template <typename It>
using it_difference_t = typename ::cuda::std::iterator_traits<It>::difference_type;

template <typename It>
using it_pointer_t = typename ::cuda::std::iterator_traits<It>::pointer;
}

and replace all uses of thrust::iterator_xxx traits which have a replacement in libcu++. Then, those thrust traits are deprecated.

The naming choice rational is here:

// the following iterator helpers are not named it_value_t etc, like the C++20 facilities, because they are defined in
// terms of C++17 iterator_traits and not the new C++20 indirectly_readable trait etc. This allows them to detect nested
// value_type, difference_type and reference aliases, which the new C+20 traits do not consider (they only consider
// specializations of iterator_traits). Also, a value_type of void remains supported (needed by some output iterators).

@miscco I may need your help here, please. Not necessarily for this PR, but we should figure out what's going on before CCCL 3.0.

The problem is ::cuda::std::iterator_traits trying to figure out some common_reference of zip_iterator when determining cuda::std::iterator_traits<zip_iterator<...>>, which I think shouldn't be needed. it works with std::iterator_traits.

Did you try std::iterator_traits in C++20 mode?

The answer is most likely that zip_iterator is cursed and we should add a specialization of iterator_traits for it

looking at you tuple_of_iterator_references

BTW I hope the issues are compile-time issues not silent runtime degradation

Did you try std::iterator_traits in C++20 mode?

Yes, it works. Tested locally and this is also what the CI should run.

Here is a reproducer: https://godbolt.org/z/7jb4qG3bb
