Polonius Alpha Borrow Checker Goes Live on Nightly, Boosting Rust Safety
Rust’s next‑gen borrow checker, Polonius Alpha, is now enabled on the nightly compiler to gather real‑world data before its slated stabilization. It adds flow‑sensitive lifetime analysis that NLL lacks, promising more precise borrow checking while keeping performance within acceptable bounds. Users can report regressions on GitHub or Zulip.
