chkservice VS systemdgenie

I wondered if there was something similar to LaunchControl that could run in a terminal. I've used chkservice on Linux, but there seems to be no macOS equivalent. I've been dying for an excuse to learn a little bit of Rust (loved n+1 years in a row by the SO developer survey2) -- so this was my chance. Several months later I ended up with launchk. The rest of this post will go over: getting started, interfacing with launchd, a lot of macOS IPC bits, getting stuck, and a bunch of probably questionable Rust FFI stuff.

There is chkservice, which runs, but it ncurses rather than true GUI and some of its actions fail with a message saying . . graphical elevation is needed. And it's a bit arcane to use. (Github page.)

SystemdGenie is quite nice.

Not exactly what you're asking for, but maybe this will suffice? https://github.com/KDE/systemdgenie

There is systemdgenie. It has a kind of pseudo-repository (here) with a link to another repository. I call one repository 'pseudo-' (and it is here) because it has no issue tracker and because it seems to direct one, via a link, to another repository; but the link is broken. And when I try to install the program, using the instructions and code on the 'pseudo-repository' (which does contain those things), a seemingly essential step in the process (the one starting cmake -DCMAKE_INSTALL_PREFIX - I can't give the whole command here because it breaks Reddit's formatting).
