Show HN: Fast `git status` (git core.fsmonitor in Rust)

How does this differ from the standard fsmonitor?

This appears to mainly be a lightweight wrapper of watchman.

In my benchmarks it's about twice as fast as the reference Perl script monitor. Also just a quick exploration for me into Rust.

You should make it clearer that the benchmark is perl fsmonitor vs. rust fsmonitor. Without reading the comments here, I would have thought it was without fsmonitor vs. with.

Good suggestion! Without the fsmonitor enabled at all that looks more like 400ms on my iMac Pro.

Thanks for the link. Yes, that makes sense. It’s also less code. :)

Edit: well, maybe just fewer comments... ha

Yes, the Perl is very short, and has more comments. I missed the Perl era so it was a bit of work for me to figure out how it worked enough to implement it in Rust.
