Sorry, those questions are mostly about rust, a topic about which I know next
to nothing. You'll have to go ask for help from the gtk-rs.org folks.
Note, however, that Gtk-osx builds a self-contained working environment that is
by design not exported to the rest of the system and which imports only the
macOS SDK from the system because its purpose is to create a build environment
that can create stand-alone application bundles for drag-and-drop installation
on other users' Macs. That's not to say that you can't use it for your rust
development, but you'll have to start a jhbuild shell and run rust from in
there. Since gtk-osx isn't intended to work with rust there may also be
additional environment variables that you'll have to set by hand; again, the
place to ask for help about that is on the gtk-rs.org support channels. You'll
probably have an easier time if you remove gtk-osx and use Homebrew or MacPorts
instead.
Regards,
John Ralls
