| __header `#include <boost/type_traits/is_detected_convertible.hpp>` |
| |
| The type `is_detected_convertible<To, Op, Args>` is an alias for __true_type if the result of |
| `Op<Args>` is convertible to type `To`. Otherwise it's the type __false_type; |
| |
| __examples |
| |
| template<class T> |
| using size_type_t = typename T::size_type; |
| |
| static_assert(boost::is_detected_convertible_v<std::size_t, size_type_t, T>); |
