boost::pfr::get — Returns reference or const reference to a field with index I in simple aggregate val. Overload taking the type U returns reference or const reference to a field with provided type U in simple aggregate val if there's only one field of such type in val.
// In header: <boost/pfr/core.hpp> template<std::size_t I, typename T> BOOST_PFR_BEGIN_MODULE_EXPORT constexpr decltype(auto) get(const T & val);
Example:
struct my_struct { int i, short s; }; my_struct s {10, 11}; assert(boost::pfr::get<0>(s) == 10); boost::pfr::get<1>(s) = 0; assert(boost::pfr::get<int>(s) == 10); boost::pfr::get<short>(s) = 11;
