Does boost support serialization of c++11's std::tuple?

Question

I couldn't find a tuple.hpp header file at /boost/serialization/

I'm using boost 1.52.0 (happy to upgrade if need be, but it seems like the changes in version 1.53 doesn't have anything related to this).

Out of the box, no. You'll have to write the serializer yourself. Luckily, someone already did:

C++0x tuple boost serialization (also in github)

Is there a solution available that doesn't use variadic templates? – jwalk Aug 13 '13 at 19:49

and here is another implementation:

with the test code :

Using C++17's fold expressions, you can easily implement a serializer:

template <typename Archive, typename... Types>
void boost::serialization::serialize(Archive &ar, std::tuple<Types...> &t, const unsigned int)
{
    std::apply([&](auto &...element)
                { ((ar & element), ...); },
                t);
}

Based on this answer.
