Richard H. Gumpertz commented on THRIFT-5497:
---------------------------------------------

[~emmenlau] : I'd like to do some more debugging before I do a pull request. 
With luck and time available, maybe it will be ready in the next few days.  In 
the meantime, would you be willing to proofread the header file I just uploaded 
today for (1) correctness (did I get the details of all the wrapper function 
definitions right?)  and completeness (did I omit any wrapper functions that 
should be included?).

The purpose of all the wrapper function definitions is to make sure that the 
wrapper type, binary_string, is returned in place of std::string where 
appropriate.  For functions that return void or iterators or such, I don't 
think any wrapper is required. 

> Change the C++ representation of binary be std::basic_string<unsigned_char>

> I would like to change the C++ representation of binary from "std::string" to 
> "std::basic_string<unsigned_char>".  This would allow C++ templates to 
> distinguish the Thrift type "string" from "binary".
> If nothing else, ::apached::thrift::to_string could print binary differently 
> than string.  Currently, it can get pretty ugly when one calls printTo on a 
> struct containing a binary field that has data that is not readable!
> There is an issue as to how they should be displayed by default; using 
> \xDE\xAD\xBE\xEF with a \ before every byte seems ugly.  Alternativlely, 
> "DEADBEEF"_x because it could also be used as input if the C++ operator""_x 
> is defined by the user?  Alternatively just <binary> or <27-byte binary> 
> (mirroring <null> for unset fields), hiding the contents?  Perhaps leave 
> to_string(std::basic_string<unsigned char> &value) undefined and force the 
> user to define it if needed?  Thoughts & suggestions???
> Given that such a change could break existing code, it should probably be 
> enabled under a new thrift compiler option to --gen cpp.  I haven't come up 
> with a good name for such an option yet: --gen cpp:binary_as_unsigned_string 
> is explicit but wordy.  Any suggestions???
> I would be willing to do the work necessary to add the relevant code if there 
> are no volunteers who have a better understanding of precisely what code 
> would have to be updated (or at least help me find such code)
