jsoncons::decode how to read in a custom class as object not array

[mrdole]

For reference this is the guide I am referencing https://danielaparker.github.io/jsoncons/
Per the reference above, I am trying to figure out how to use decode_json to read in an object in an object in a json versus using an array.

In the example it shows reading in a json file:

std::string data = R"(
    {
       "application": "hiking",
       "reputons": [
       {
           "rater": "HikingAsylum",
           "assertion": "advanced",
           "rated": "Marilyn C",
           "rating": 0.90,
           "confidence": 0.99
         }]
    }
)";

I need to read in:

std::string data = R"(
    {
       "application": "hiking",
       "reputons": 
       {
           "rater": "HikingAsylum",
           "assertion": "advanced",
           "rated": "Marilyn C",
           "rating": 0.90,
           "confidence": 0.99
         }
    }
)"; 

Where reputons is just being read in as an object.

So in the example it is setup such that:

class hiking_reputation
    {
        std::string application_;
        std::vector<hiking_reputon> reputons_;
    public:
        hiking_reputation(const std::string& application, 
                          const std::vector<hiking_reputon>& reputons)
            : application_(application), 
              reputons_(reputons)
        {}

        const std::string& application() const { return application_;}
        const std::vector<hiking_reputon>& reputons() const { return reputons_;}
    }; 

When I tried to convert to just read the hiking_reputon class I get an error:

class hiking_reputation
    {
        std::string application_;
        hiking_reputon reputons_;
    public:
        hiking_reputation(const std::string& application, 
                          const hiking_reputon& reputons)
            : application_(application), 
              reputons_(reputons)
        {}

        const std::string& application() const { return application_;}
        const hiking_reputon& reputons() const { return reputons_;}
    }; 

Is there a specific way I need to setup the class to read in an object instead of an array?

Just tried it, and it looks like hiking_reputon requires a default constructor for that case.

Doh! Yep that was it. Just set a blank default constructor and it works! Thanks!
