I hope this kind of thing means Rust stops making so many rapid breaking changes in th compiler. I've tried it twice, once in early 2021 once 2025. Both times I tried to compile a few random projects I found on the web, stuff like a wordpress fanfic scraper, a software defined radio program, etc. In 2021 my linux distro I was using had just been released 3 months prior but it's rustc already could not compile 2 of 3…
It sounds like you are not running into breaking changes, you are just running into projects that like to use new features that are not available in your older compiler.
Re: Rust is tier-1 language at Microsoft
#521Correct. From the point of view of a stable desktop LTS system the code that the typical rust developer writes breaks within a few months as it starts using features from latest that are forwards compatible.
