C++14/17 type_traits Часть 3.

В предыдущей серии мы изобретали нечто, называемое XXX_traits, где под XXX скрывается какой-то концепт. А сам трейт описывает, какие операции доступны для типов, реализующих данный концепт. И все взаимодействие с шаблонными параметрами происходило с помощью вспомогательной структуры.

template <class T, class S>
auto accumulate(const std::vector<T>& arr, S&& op) 
    -> RESULT<T>::REQUIRES<SummatorTraits<S>::value> {
    using STraits = SummatorTraits<S>;

How to trick "Qt Maintenance Tool" to install old versions

tl;dr

Use a software like mitmproxy to modify the (https)-request to iapi.qt.io/api/v2/repositories so it's response lists the old Qt directorys that are still on the servers.

If you never used mitmproxy before here is the guide that shows you how it's done.

C++14/17 type_traits Часть 2.

В предыдущей серии мы пытались сделать нечто, напоминающее проверку концепции C++20 средствами C++14/17.

У нас была функция sum, от типов аргументов которой мы требовали применимости операции +. И выглядело в конечном итоге это так:

template<typename T>
auto sum(T a, T b) -&gt; RESULT::REQUIRES&gt; {
