[jira] Commented: (THRIFT-539) struct hash and print methods for C++

["Nitay Joffe (JIRA)" <ji...@apache.org>]

Nitay Joffe commented on THRIFT-539:
------------------------------------

True, but you can't just do e.g. "cout << myStruct << endl;" which I've found helps a lot in debugging.

> The current thrift compiler for C++ generates methods for structs like operator== and operator< since it uses maps,sets, etc but it does not generate a hash() method or a human readable print() method.
> The idea of this issue is to add functionality to the C++ compiler to generate:
> # A boost hash compatible hash_value() function. This should probably be an option to the compiler as it adds a dependency in generated code on boost.
> # An operator<< function for printing structs in a nice form. This should be safe to always do?
