Rust seems to provide memory safety built-in that is still possible in C++ with appropriate linters / static analysis (e.g., don't ever assign a `new` pointer to anything other than a unique one). I remember Google's codebase generally being good on this, but does Chromium not follow that?

My guess is yes and these are issues that would affect both languages equally, with Rust it just happens to be in an `unsafe` block.
