You can use something like `no_panic`[1]. You could also do it statically, post-build, by looking for calls to the panic handler. [1]: https://docs.rs/no-pani

  Does annotating `main` with no_panic do the trick? How much does that tend to affect compile times, do you know?

IME, not very much -- there might be a small amount of overhead, but the "trick" behind the check is to fail the linker with a symbol error if the panic code is inserted into a function. So the compiler itself should be roughly as fast, and the error path in the linker is really the only thing that should change too much.
