If my github api-fu is correct that's what, 40kloc for the rust side of things? Doesn't seem unreasonable times (vs C++) for a full rebuild on that machine - which I'd generally want to do for anything but the most trivial C++ toolchain bump too (in fact, I'm usually forced to) making a comparison against incremental builds very apples-to-oranges IMO. What's your C++ LOC/full rebuild like? I'm used to ~100kloc of C++ taking half an hour per config+platform on a 4-6 core, 16GB+, SSD machine. Less hygenic than your codebase sounds like, but with some beefy PCHs. Toolchain updates are usually a full day affair in this context, although that's not entirely from just the compiler bump. Of course, incremental vs full rebuilds are no contest. Rust is at least working on incremental builds now that they have MIR AFAIK. And binary cargo support would be really nice as well. As would be compiling in general.
