#How to: multiple names for one field?

Can you link to the exact requirements the function has?
Which function in that file?
Okay, but can you show me your code? What function are you calling or what template are you instantiating?
I'm more interested in this over the exact place where it fails internally
The value_type of the edge iterator must be a std::pair (or at least have first and second members). The first_type and second_type of the pair must be the same
So while you don't have to use std::pair, you'll have to rename the members to match it, and add the first_type,second_type typedefs

How to: multiple names for one field?
slate rampart
There's no good way to have multiple member names in a struct. But that's not necessary I think, because you can write a really clever iterator
I'm not sure if there's a builtin iterator for that, but you can write one where operator* returns by value something like struct Blah {std::string &first, &second; using first_type = std::string; using second_type = std::string;};
If this library is written properly and can handle operator* returning by value, this should just work

Wouldn't a conversion operator work? I mean converting MyObject to std::pair
slate rampart
No, because even with that operator my_obj.first wouldn't compile
