> C++ full builds scale better than Rust
Chromium has millions of line of code not 17k, so, although the scaling test is fairly artificial, rust might get worse and worse as the project get bigger.
Paradoxically, the stupid include model of C++ allows to extract more parallelism form the build.
I wouldn't be surprised if C++ with modules has similar scalability behavior as rust though.
Longer than? C++?
