Huh?!?!?!
I don't know about Rust (I know they like their install script), but for Go you can download a pre-compiled binary and you're instantly up and running. That option is not exactly hidden[1].
You don't even have to use an OS installer, e.g. for Linux/Mac you can download a .tar.gz file[1] unzip it anywhere and just run "go" based commands to compile stuff immediately (maybe adding it to your $PATH to make life easier).
But really. Go is a million times quicker and smaller than usual bunch of stuff you need to install to get a C thing compiled (and that's just the standard tools, before we start talking about random stuff like Meson or Ninja)
The point I was making is that Ipcalc is a simple CLI utility. It doesn't need all the baggage that comes with C compiling. Its practically made for Rust or Go.
You can also easily cross-platform compile with Go. Try that with C without jumping through hoops !
