Hi, I'm building a small tool to detect code injection in Unity assemblies, and I'd like to use compiler directives for debug and release builds. Something like; #[cfg(build = "debug")] fn do_something(){ // Output sensitive debugging info } #[cfg(build = "release")] fn do_something(){ // Don't o…

Still looking for a good way to do this. I'm surprised nobody else is interested in conditional compilation for debug and release builds.

[image] stebalien: cfg(debug_assertions) Thanks. How did you know about "debug_assertions"? I read through the reference and doco but never came across that one.

I looked at the source code for the debug_assert macro (so this cfg may not be very stable).

There really should be a #[cfg(debug)] currently you can define something like #[cfg(feature= "debug")] but you than have to manually add --features debug to your cargo build. On the other hand, I can see why you would want an explicit call. edit: hihi, I misjudged the age of this thread, reading …

You can use the following build script use std::env; pub fn main() { if let Ok(profile) = env::var("PROFILE") { println!("cargo:rustc-cfg=build={:?}", profile); } }

The debug_assertions config option seems to be the legit way to do this. It is mentioned in the rust reference: https://github.com/rust-lang/rust/blob/master/src/doc/reference.md#conditional-compilation And it is mentioned in the cargo docs: Page Moved

You can use cfg(debug_assertions) but there should probably be a cfg(debug).
