| inline static
  Creates a JSON object value from a given initializer list. The initializer lists elements must be pairs, and their first elements must be strings. If the initializer list is empty, the empty object `{}` is created. Note This function is only added for symmetry reasons. In contrast to the related function array(initializer_list_t), there are no cases which can only be expressed by this function. That is, any initializer list init can also be passed to the initializer list constructor basic_json(initializer_list_t, bool, value_t). Parameters
  [in] | init | initializer list to create an object from (optional)
  Returns JSON object value Exceptions
  type_error.301 | if init is not a list of pairs whose first elements are strings. In this case, no object can be created. When such a value is passed to basic_json(initializer_list_t, bool, value_t), an array would have been created from the passed initializer list init. See example below.
  Complexity Linear in the size of init. Exception safety Strong guarantee: if an exception is thrown, there are no changes to any JSON value. Example The following code shows an example for the `object` function. 1 #include <iostream> 2 #include <nlohmann/json.hpp> 3 4 using json = nlohmann::json; 5 6 int main() 7 { 8 // create JSON objects 9 json j_no_init_list = json::object(); 10 json j_empty_init_list = json::object({}); 11 json j_list_of_pairs = json::object({ {"one", 1}, {"two", 2} }); 12 13 // serialize the JSON objects 14 std::cout << j_no_init_list << '\n'; 15 std::cout << j_empty_init_list << '\n'; 16 std::cout << j_list_of_pairs << '\n'; 17 18 // example for an exception 19 try 20 { 21 // can only create an object from a list of pairs 22 json j_invalid_object = json::object({{ "one", 1, 2 }}); 23 } 24 catch (json::type_error& e) 25 { 26 std::cout << e.what() << '\n'; 27 } 28 } Output (play with this example online):
      {}
      {}
      {"one":1,"two":2}
      [json.exception.type_error.301] cannot create object from initializer list
  The example code above can be translated with
      g++ -std=c++11 -Isingle_include doc/examples/object.cpp -o object
