cxx_name attribute - function aliases, import/export static methods, …

[VKachemtsev]

I found a better solution for #218: cxx_side attribute
Features:

• Renaming functions/methods in C++ and Rust
• Import overloaded functions/methods
• Export/import static methods from both sides

In the future we can add new features for this attribute: replace return type to UniquePtr/Box, implement constructors, etc.

Thanks; I think the other approach is more promising to me though. I see that you noticed that #[cxx_side(name = "method", class = "C", static)] can be condensed to #[cxx_side(name = "C::method", static)]. But that's still a lot of redundancy because whether the method is a static member function or non-static member function is clear from whether it has a self: &C / self: &mut C first argument. And once you are down to #[cxx_side(name = "C::method")] that is just needless annoyance over the other style which was #[cxx_name = "C::method"].

Closing in favor of #218.

Thanks anyway!

Hi, currently it is impossible to do #[cxx_name = "C::method"] for the static member function method of C. What is the workaround?

[jon-chuang]

I guess the workaround is to wrap in non-static function. Thanks!
