I agree with this, I've encountered some of these, especially this:
> Streamline seeds. There are some hardcoded seeds, but it's unclear how to
call a function with arguments to get the same error-inducing dataset. It'd
help to include a hint on how to generate a test batch for debugging
I'm thinking the plan would be to:
1. During failure we either set a environment variable to the seed and have
it rerun, or print it out (or both)
2. Reproduce the dataset with the saved seed + save it to an arrow file
Something like (example where seed = 1 failed):
``` FUZZ_SEED=1 cargo test fuzz_case_example```
3. Have a reader for the arrow file
4. Add documentation to show how to do this in `fuzz_cases`
