TIL that Rust has a (i) icon that shows relevant traits that a type implements. This is useful to understand that e.g. .iter() on a Vec<T> iterates with &T. https://doc.rust-lang.org/std/vec/struct.Vec.html#method.iter It looks like one of my bug reports was mentioned, so I'm delighted but wish I'd noticed earlier!

Rust gotcha I haven't seen before: you can't move out of a vec by index, even if you own the vec. This is because it'd leave the vec in a bad state: you need .remove() or .pop() instead.

I feel like Rust often pushes me to use concrete types. It's a lot easier to return a Vec than an impl Iterator. It's not a big problem, but in e.g. Java I'd just say I'm returning some kind of iterator.
