I have installed relatively simple-looking GUI apps from AUR. They seem to be written in Rust. The problem is that they took a lot of time to install. In the details, I see messages like below. Does it have build all those on my computer? I mean, doesn’t Rust already have compiled GTK libraries? Why can’t the app use it, instead of compiling everything?
