“With roughly 5 million lines of Rust in the Android platform and one potential memory safety vulnerability found (and fixed pre-release), our estimated vulnerability density for Rust is 0.2 vuln per 1 million lines (MLOC).”
Five million lines in Android produced one memory safety bug, caught before release. The people arguing Rust is unsafe because the word unsafe appears in it are arguing about vocabulary. Meanwhile the C codebases they are defending ship the same three bug classes they have shipped since 1978.
