Just to add to this point, the difference is that Rust can only guarantee this for the standard library. I can similarly write a library with safe interfaces that can be (ab)used to cause UB and there's little that the Rust team can do. This is different from other "safe" languages.
This is why it's so important to establish what the responsibility and expectation is of library developers to uphold the safety guarantees that everyone else relies on. It only takes one bad library to destroy the safety guarantees everyone who is transitively using that library relies on.
