Detailed Description

template<class Iterator_t>
requires std::derived_from< Iterator_t, mysql::iterators::Iterator_interface<Iterator_t>> && mysql::iterators::Is_legacy_input_iterator_impl<Iterator_t>
struct std::iterator_traits< Iterator_t >

Specialization of the standard library customization point std::iterator_traits, to subclasses of Iterator_interface.

This deduces the iterator category and defines other type members required for iterators to satisfy the standard library requirements for iterators. See also the "Specializations" section at https://en.cppreference.com/w/cpp/iterator/iterator_traits
