Rust (Backend)

Microsoft reported in 2022 that roughly 70% of the security vulnerabilities they patched in the year prior were memory safety issues — exactly the class of bugs Rust prevents by design. They've since committed to Rust for new systems-level code. The Linux kernel accepted Rust as a second official language in 2022.

Reframes Rust compiler errors as three-part messages (location, summary, explanation) and shows that reading the explanation typically uncovers the real bug faster than patching with `clone()`, citing a 60-engineer team where instituting 'read the compiler error first' dropped median PR review cycles from 2.4 to 1.6. Walks through the seven most common errors (borrow of moved value, cannot borrow as mutable, lifetime mismatch, type annotations needed, trait bound not satisfied, use of moved value in async, async closures unstable in 2026) plus the E0597 and E0277 deep dives, with `cargo fix`, `rustc --explain`, and `cargo expand` as the meta-tools.
