I keep looking to play with Rust more, but the level of churn in the language is still rather high. The future looks bright though.

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.
