After a bit more tinkering that expected, I’m finally (almost¹) releasing my first Rust crate!

rust-bisect helps track down when a change—usually a bug!—was introduced into Rust. Rather than git bisect directly on the Rust repository, it uses nightly builds to speed up the process. This is faster in at least a couple of ways:

• at over 100 pull requests merged per week, there are far more commits to bisect than there are nightly builds
• to run an individual test, all rust-bisect needs to do is download the nightly: no slow Rust build at each step!

This was a really fun project to work on! I made a few changes to related crates, and even had to solve a stereotypical algorithms interview problem. And of course, there’s something extremely satisfying about seeing it bisect and actually find the right nightly…

Try it out!

If you want to give it a shot, check out the repository—especially the example! I’d really love to hear if this is useful to you. And please open issues if you come across any bugs!
