    I can show you a real world example: https://github.com/hyperledger/iroha The C++ version compiles in 3 minutes. The rust version takes 15, and the Rust version isn't even complete yet. Moreover, the target dir grows to sometimes in excess of 50GiB, if you have debug symbols, several features and incremental compilation. C++ by contrast keeps it in the low 8GiB which allows me to mount it to tmpfs.
