> In the Rust snippet vector is moved into the loop, and thus freed.
Do you see any code in the snippet that requires it to be? This could be a simple read-only borrow because the actual logic of the program requires only that, and the value could live on happily after the loop. Literally nothing in this snippet requires anything else, you've just sort of assumed that the way Rust does it is the only thing that makes sense.
It's not about what Rust currently does, really, it's about what it ought to do.
