leaky-repo VS knob

Also, I've built a repo of credentials and benchmarked several tools including trufflehog against it if you want to see how your tool and default ruleset stack up: https://github.com/Plazmaz/leaky-repo

At this point, we've succeeded at what we set out to create. I went ahead and scanned common testing repositories for this sort of thing like Plazmaz/leaky-repo and dijininja/leakyrepo. In general the program found all or most of the secrets. In the case of dijininja/leakyrepo it found a lot of RSA private keys which is acceptable but technically a misidentification. For Plazmaz/leaky-repo we find the majority of the keys although once again misidentify some. The decision to use rust makes performance really solid although still a little slow even for small repos. A couple good extensions to this to help with that could be adding a thread pool in order to scan objects in parallel. In more professional code, it seems more idiomatic for the scan_objects() function to return some objects of objects including their results rather than just printing the one containing secrets. For example, it could be formatted something like this:
