(disclaimer: I work on Fuchsia, not speaking on behalf of my employer, feel free to clone the source repo and make your own analysis)
FWIW, to the best of my memory as of a year ago I counted ~1.1 MLoC of Rust code in our open source tree, with an additional ~1.3 MLoC in things we've vendored from crates.io.
There was a bit more C++ when I did the analysis, but it was the same order of magnitude.
Good to hear. A few years ago, there was a team advertising on grow/ for Fuchsia & Rust (for networking stuff I think), and they advertised in Waterloo but when I inquired, the posting went away and I was told they weren't actually hiring at my site. shrug Maybe it was my bad breath.
Other than that... Fuchsia was the thing that was rewriting all my work from scratch and killing everything I worked on (Chromecast on Home Hub, etc), so... :-)
