A big part of what makes Rust great is that it catches those issues at compile-time, no test coverage required, no extra run-time checks required (not that it moots tests, of course). In my experience so far this is a very powerful ally to have when writing software, as it's very useful to surface those issues as early as possible. EDIT: Also: > Assuming that tests exist, and have good coverage That's a very big assumption. Granted my current job is often to clean up codebases that are the opposite of that, so maybe I've got a bias here.
