Fearless Refactoring
summary
Rust reduces long‑term maintenance cost with concrete numbers: maintenance effort ~50% lower, upgrades and refactors ~30% cheaper, and overall lifecycle cost about 2/3 of other languages in the presenter’s estimate. Team used Rust across embedded and Linux stacks at Roxys, using Cargo, embassy on bare metal, enums/match, Option/no‑null, ARC vs Rc, and the borrow checker to catch thread and memory issues. A four‑person Rust team reports productivity comparable to six in prior stacks.
