It looks like most of this is just reformatting, except for the last line that makes it handle the case where scan_link_label_rest scans the entire file and points it at the end (replacing bytes[2 + len] with bytes.get(2 + len)).

Yes, that's correct! I have my editor configured to run rustfmt automatically, so the entire file had lots of changes after my edit. I staged the relevant hunk and reverted the rest. I'm now to the project, so I don't really know the preferred style yet, but I figured the long chain of && was easier to read this way.
