No, not really, but you could have, if you are here it means you have built a Rust crate that uses this crate as a dependency and I wanted to showcase that any [proc macro](https://doc.rust-lang.org/reference/procedural-macros.html) can run arbitrary code in your machine simply by building a a crate that depends on it or even just opening it on your editor (because of [rust-analyzer](https://github.com/rust-analyzer/rust-analyzer)), depending on your threat model you might not care much about this or you might care a lot, it's up to you to take steps if you feel like this is a credible attack vector.

You may also want yo know that this "exploit" won't work upon opening the file in your editor if you are using [rls](https://github.com/rust-lang/rls).

If you were linked here, you can clone this repo and open it in your editor to see if you are vulnerable.
