What’s so special about Rust 1.49, you ask? It’s the first release of Rust, ever, to officially support the ARM64 architecture. Meaning it would officially be supported on the Raspberry Pi.
This just seems like the most Debian thing for some reason. Seriously though, I can’t imagine this is a large or disruptive change. I could see it still getting in before milestone 2. I guess email the teams involved and let them know.
Although I’m a long-term user of Debian Stable, I haven’t had a chance to look at what to expect yet in the upcoming release 11. From what I know of Rust, it appears to be an excellent language for systems development. I’m also interested in the OS being developed using it. Unfortunately my skill-set isn’t high enough to support its inclusion in Debian 11 directly at this stage, but thanks for bringing it to our attention. Hopefully someone in our community is able to help.
