conditional compilation #2

Open chuqingr opened 7 months ago

Hi, I've been studying this recently, and I've come across a tricky question。How do you use conditional compilation in rust? For example, attribute((annotate("annotation")) in c++？

Hello, Im not sure how to do it. Maybe you can use #[cfg_attr] or similar in Rust. It would be useful to select functions to obfuscate but I dont know.

Hello,Thanks for your reply. At present, it seems that #[cfg_attr] & #[cfg] can't take effect. proc_macro may be needed, but it is troublesome to use https://github.com/rust-lang/rfcs/blob/master/text/1566-proc-macros.md
