! @brief returns the maximum possible number of elements Returns the maximum number of elements a JSON value is able to hold due to system or library implementation limitations, i.e. `std::distance(begin(), end())` for the JSON value. @return The return value depends on the different types and is defined as follows: Value type | return value
