I ran AFL on rust-brotli for a week a couple weeks ago. It didn't find anything. I plan to try again soon! No one is safe from AFL.

Have you run AFL against git2-rs? I'd love to see that interface hammered on, to make sure it doesn't expose any unsafe behavior from the underlying library.

I haven't, though I've thought about it. Most of the logic behind git2-rs (as far as I know) is written in C. While it's possible to run afl.rs on a Rust project that uses C code behind the scenes, I haven't ever attempted to get AFL instrumentation working on the underlying C code. I don't think it should be that difficult, I just haven't gotten around to it yet.

EDIT: I forgot to mention: It's possible to run AFL on uninstrumented code, it just won't be that smart about finding new code paths.
