You may be interested in applying Kani if you're in this situation:
- You're working on a moderately important project in Rust.
- You've already invested heavily in testing to ensure correctness.
- You want to invest further, to gain a much higher degree of assurance.
If you haven't already, we recommend techniques like property testing (e.g. with
proptest) before attempting model checking. These yield good results, are very cheap to apply, and are often easier to adopt and debug. Kani is a next step: a tool that can be applied once cheaper tactics are no longer yielding results, or once the easier to detect issues have already been dealt with.
