conditional compilation

[chuqingr]

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. Similar question: https://users.rust-lang.org/t/custom-attribute-annotations/65063 Ysh ***@***.***> escreveu no dia quarta, 13/12/2023 à(s) 09:11:

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
