- Postcondition
*this
has the same value as other before the call.
-
other is a JSON null value.
- Complexity
- Constant.
- Exception safety
- No-throw guarantee: this constructor never throws exceptions.
- Requirements
- This function helps
basic_json
satisfying the MoveConstructible requirements.

2 #include <nlohmann/json.hpp>
15 std::cout << a <<
'\n';
16 std::cout << b <<
'\n';
Output (play with this example online): null
