Highlights from This Week in Rust - Issue 444. This week features a juicy post-mortem, open source, open hardware, and lots of news from around the Rust ecosystem.

Twitter: @rustaceanfm Discord: Rustacean Station Github: @rustacean-station Email: hello@rustacean-station.org Timestamps & referenced resources [@00:00] Welcome [@00:10] - Introduction [@00:50] - Agenda [@01:23] - Quote of the week This is the difference in approaches of the two languages. In C++ if the code is vulnerable, the blame is on the programmer. In Rust if the code is vulnerable, Rust considers it a failure of the language, and takes responsibility to stop even “bad” programmers from writing vulnerable code. I can’t stress enough how awesome it is that I can be a careless fool, and still write perfectly robust highly multi-threaded code that never crashes. [@03:09] Allen: Rust is both good and bad at marketing [@03:30] - Crate of the week [@04:15] - Tim and Sean discuss parsing in episode 2022-05-26 at 47:10 [@05:10] Official Notices [@05:22] - Announcing Rust 1.61.0 Custom exit codes from main [Note from Tim: I say “termination crate”, but should have said “Termination trait”.] More capabilities for const fn “Basic” handling of fn pointers Add trait bounds to a const fn dyn trait and impl Trait support Stdio handles can be locked directly Several stabilized APIs [@08:07] Highlights [@08:27] - Developer survey: JavaScript and Python reign, but Rust is rising [@09:09] - Sean: “Rust adoption has nearly quadrupled in the last two years, going from 600k developers in Q1 2022 to 2.2m in Q1 2022.” [@13:00] - Redust by Will Nelson [@13:50] Allen: I think the comments are actually more interesting. They are starting to point to something really—I don’t know whether it’s good or bad for the community—where, you know, people start rolling their own crates instead of, say, doing stuff upstream. It kind of goes back to what Tim was complaining about before [Easy Mode for Rust, discussed on This Week in Rust - Issue 441]—well, lightly pointing out to people out there—that okay, now which crate should I use? [@16:20] Tim: Open source is really complicated. You need to talk to people. That’s … challenging. [Laughs] [@16:40] Josh Triplett on Building with Rust, discussing the orphan rule [@16:50] Sean: Rust is not very good at sharing between crates. [@19:07] - Rust: A Critical Retrospective by bunnie Links The Hardware Hacker, bunnie’s autobiography [video] “Shenzhen: An Alternative to the American way of Innovation” [@28:56] A Programmer’s Brain, by Felienne Hermans, about working memory in programmers.

There’s one quote I want to pull out of the post, which is: “I’m not sure if there is even a good solution to this problem, but, if you are super-paranoid and your goal is to be able to build trustable firmware, be wary of Rust’s expansive software supply chain attack surface!” [@26:09] - Sean: bunnie I think that you are absolutely, totally, qualified. [@30:17] - Allen: I did see a macro that he put in there. … I forget extact. It was very crazy and I was like, “Come on, no one’s every going to write something crazy like this” and then I took a look at the RFC that Sean’s gonna do and in the comments there was a crazy one like that and I was like, “oh wow, this guy’s point’s valid”.
