Rust is very niche within FB and not used by the overwhelming majority of teams. It is less important to FB than C++, Python, Objective-C, Java, Hack, and Ruby.
That said, yes, it’s used some, but that reflects a few random teams having decided to use it (most notably hg and Libra), not some grand strategic decision.
Source: I worked at Facebook for four years, until one year ago.
(Incidentally, I’ve spent the year since then working exclusively in Rust for my day job, and I love the language)
