>it doesn't leak memory

Fairly sure you can leak memory, just no memory safety issues (in safe Rust).

You can also cause segfaults, the point I think is more that it is hard to do this instead of easy as it is in some languages, like C.

Memory leaks can happen in safe code, segfaults cannot. That’s at least one major difference.
