> Just like thrift objects implement a custom toString in Java, there should be an inline friend function that writes a text representation of the struct to a std::ostream.  Probably makes sense for the text representation to be similar to C++:
> {code}
> class MyThriftClass {
>     friend std::ostream& operator<<(std::ostream& o, MyThriftClass) {
>         o << "MyThriftClass[";
>         o << "field1=" << field1;
>         if (__isset.field2) {
>              o << ", field2=" << field2;
>         }
>         o << ", list1=" << apache::thrift::util::to_string(list1);
>         return o << "]";
>     }
>     // ...
> }
> {code}
> There will also probably be a util.h file to include that implements generic template to_string for lists, maps, & sets.
