That was interesting indeed, thanks. For an outsider, the most trivial takeaway from that is something along the lines of "Rust is slow to compile and it's probably not getting 10x faster any time soon". Beyond the obvious culprits like heavy metaprogramming, it looks like death by a thousand cuts (not to mention that ggez spends 15 seconds on something that's not even accounted for in the profile, that alone is huge) and there obviously isn't a common root cause for huge compile times in general.
