    Nice, I just would have liked to get all these different verification tools combined under the same interface, just being different backends as drafted by the rust verification tools work of project oak: have "cargo verify" as common command and use common test annotations, allowing the same test to be verified with different backends or just fuzzed/proptested.

    The model checking approach seems to be a bit limited regarding loops. There are also abstract interpreters, such as, and symbolic executers, such as or

    Overall I believe this space would benefit from more coordination and focus on developing something that has the theoretical foundations to cover as many needs as possible and then make a user-friendly tool out of it that is endorsed by the Rust project similar to how Rust analyzer is the one language server to come.

    When we talk about formal methods being used in the industry I honestly think Galois' approach is the future. The main idea is to symbolically execute llvm code and run a SAT solver on the desired properties. See Crucible and SAW.
