Regarding using stable builds of Rust with afl.rs: If I could, I would.

afl.rs uses a Rust compiler plugin to register the LLVM pass needed to instrument Rust programs so that AFL can run on them:

Compiler plugins in Rust are currently unstable, and as far as I know, are not on a path to stability in the near-term.

It doesn't need to use llvm_mode. You can do what gcc does and have an afl-gcc binary which mucks with the assembly instead of actually inserting hooks smartly. This isn't as good, but works without nightly :)

Huh, wasn't aware that's how afl-gcc worked. I'll have to look into it sometime, thanks for making me aware of it.

Depends on how you define "near term." It's being actively worked on, but is still gonna take a while.
