Я пытаюсь использовать boost MultiIndex контейнер в общей памяти, я использую функцию replace для обновления записей при попытке компиляции компилятор жаловался на оператор = так что я перегрузил оператор =, как показано в приведенном ниже коде, однако, похоже, что ошибки компиляции, которые возникают, связаны с распределителями. Это первый раз, когда я использую собственный распределитель для общей памяти. Есть ли что-то особенное, что нам нужно делать, перегружая оператор = для строк с помощью специального распределителя?Как перегрузить оператор присваивания для строк, которые используют пользовательский распределитель

У вас есть работа в гораздо более простом случае? Как вектор, использующий этот распределитель? Потому что я вижу сразу три разных сложных события, которые кажутся плохим способом создания рабочего кода. – Yakk
Стандартные контейнеры STYYYKK не обеспечивают функцию замены. Таким образом, эта функция специфична для контейнера с несколькими индексами в boost. – deb
Вы действительно не хотите перегружать оператор присваивания (также, 'std :: basic_string <> :: assign') – sehe
