The authors bupstash[1] tool looks interesting.

I see there's an issue made for Windows support, how is that with Rust?

Unless it's doing low-level stuff like directory monitoring I assumed Rust would be quite portable?

Windows is generally well supported by Rust and its ecosystem; this package seems to be using platform-specific flags in some cases, without trying to do it in a more platform-agnostic way. Doesn’t mean it can’t be done, of course.
