The comment you linked says something specific about a specific kind of bug being eliminated - memory safety bugs. And they’re not making a claim, they’re repeating the evidence gathered from the Android codebase. So that’s a fact, memory safety bugs truly did not appear in the Rust parts of Android.
The comment you linked is not claiming Rust code is bug-free. That’s a strawman I’ve seen many, many times. Haters will claim that this happens all the time, but all I see are examples of the haters claiming this. You had to go back 5 months and still couldn’t find anything similar to the strawman.
> This one probably covers it
No, probably not.
