lucascs@protonmail.com Lucas C.S. cargo-geiger walks the dependency tree and counts expressions inside unsafe blocks, per crate. It is a triage aid, not a verdict: unsafe is legitimate in low-level crates, and the count says where to look rather than what is wrong. Upstream activity has been low since 2025 -- the newest release, 0.13.0, is from August 2025. https://github.com/geiger-rs/cargo-geiger/issues geiger-rs/cargo-geiger
