Do not include #[test] functions

[snaulX]

I create tests for bindings in the same file with bindings themselves (or else it gets me a lot of troubles with visibility). And these test functions are includuded in bindings for C# so maybe don't include functions with #[test] attribute? Or maybe even include only functions with #[no_mangle] attribute? I can make pull request if this feature is needed.

The only current extraction is the extern method.
Is this is almost identical to no_mangle?

As I know, no_mangle disables Rust name mangling for the function, so it will have a normal name without internal compiler information. So we remove functions with '"strange names" from bindings as we check it on no_mangle.
Also I think that there's need check of pub visibility because else function just will not be showed in dll as exported.

Thanks for the suggenstion. I think you are right that we should check for no_mangle.

• However, for #[test], it should not be covered without extern.
• Also, the pub access modifier is also a visibility on Rust and should not be covered by ffi.

I have made a fixing to your point #66 . I also commented here #60 (comment). I hope you will check it.
