It can eliminate many bugs, but it certainly wouldn’t eliminate all bugs. During implementation they realized they were not implementing sudo’s (undocumented) feature of failing to run if the sudoers file is world-writable: https://ferrous-systems.com/blog/testing-sudo-rs/.
Of course they did find and fix the bug, but in general Rust isn’t going to protect you from bugs like this that are essentially logic errors.
