There are many other kinds of proof objects https://www.philipzucker.com/proof_objects/ . A similar one that is useful is outputting a permutation from a sorting algorithm. Verifying a permutation takes O(n) but sorting under the appropriate assumptions takes O(n ln(n)), so there is a complexity gap there. https://cacm.acm.org/research/program-correctness-through-self-certification/

With the U.S. at war, a volatile stock market and increased fears of a 1970s-style stagflation—not to mention leaders like Block CEO Jack Dorsey already citing AI as a reason to slash headcount—it’s worth pausing to contemplate what’s really behind the job cuts. Nailing down the root cause will shape the perceptions and policies around unemployment, and the ability of leaders to do something about it. A few points that I think about:。业内人士推荐新收录的资料作为进阶阅读
In this case, the behavior is an implementation detail, not particularly defined nor explained anywhere. The mutex is an off-the-shelf parking_lot::RWMutex, from the parking_lot crate. It has eventual fairness, which means that readers will eventually acquire the lock, even during high write-throughput scenarios. They will be randomly delayed, though, up to 0.5ms. The parking_lot crate is a Rust port of WebKit’s original WTF::Lock — this 2024 changeset shows how eventual fairness was implemented there. You should read it, it has very good performance insights on mutex contention. Think of it as a palate cleanser from this blog post. Now back to the hash table & the lock.，推荐阅读新收录的资料获取更多信息
