Concept definition

template<class Test>
concept mysql::iterators::Is_declared_legacy_forward_iterator = 
    std::derived_from<typename std::iterator_traits<Test>::iterator_category,

Detailed Description

True if the iterator is declared to meet LegacyForwardIterator requirements.

Note that this does not check the requirements (not even syntactic ones): an iterator that lies about its category will fool this function. However, an iterator defined using Iterator_interface is guaranteed to satisfy the syntactic requirements.
