Assign to this object the value resulting from first clearing this vector and then inserting (in order) each VALUE_TYPE object in the specified values initializer list, and return a reference providing modifiable access to this object. If an exception is thrown, *this is left in a valid but unspecified state. This method requires that the (template parameter) type VALUE_TYPE be copy-insertable into this vector (see {Requirements on VALUE_TYPE}).
