re: rust (early impressions)
And my rust-produced executable is a lot bigger than I expected. That's also the sort of thing I only noticed because of this low-footprint goal; it's a concern that will vanish as you move into medium-size programs.
I'm enjoying this as a learning exercise, but practically speaking, is it a good fit for this case?
Maybe should have stuck with Python, assuming there's a shared instance of it already installed on the target. Which would be true of pretty much all Ubuntu-derived installations (it's in ubuntu-core), but maybe it's not as core to Debian as I thought, and it's unclear what runtimes will be available to future versions of OS X. 🤷
Making guesses about portability is hard!
(The initial impetus for this utility was something I couldn't figure out how to make readable in POSIX sh/sed/awk.)
