If you go into the parent directory, what appears to be the main Gabeldorsh directory, most of the implementation appears to be written in C++. Is the project being slowly rewritten in Rust? Or are only parts of it written in Rust?
The headline is technically correct. "rewrite with Rust" means there is Rust inside, but it doesn't mean that it's all (or mostly) Rust. But given the way one commonly understands the headline, it's definitely misleading.
