What proportion of Rust v1.0 code still works on the latest version? Almost all of it, but we have hard data!

Hi folks. We care about not breaking code and put a fair bit of effort into it: we have policies about acceptable breakage; compile new versions of Rust against downstream code; track regressions (somewhat) carefully on the issue tracker, fixing most of them before they hit stable releases; submit patches to downstream projects when we do break them; report breaking changes in commits and release notes. When you consider that Rust, unlike any other language, publishes new revisions every 6 week...

It's really satisfying fixing crashes in rust-analyzer. You can start from a panic message and dig until you've got a tiny Rust program that triggers the problem. (It's usually an issue with incomplete source files breaking invariants.)

Previously rust-analyzer assumed that a module always had an item list, which isn't true for unresolved modules. Handle this situation gracefully instead of panicking, and add a test. AI disc...

Today I learnt about clippy::clone_on_ref_ptr, which complains about t.clone() on a Rc<Thing>. You write Rc::clone(t) instead, so it's obvious it's a cheap clone. It's a nice approach, because it makes the expensive clones more obvious.

It's funny how languages can offer multiple forms of syntax, but formatters standardise to a single form. E.g. single vs double quotes in JS, optional semicolons in JS, different ways of grouping imports in Rust. Should new languages be more syntactically opinionated?
