Have you spoken with the Rust core team about Microsoft's use of actix? They love getting feedback from commercial users, and I believe they are willing to sign NDAs when necessary (there's certainly plenty of commercial users they seem to be unable to tell me about, and I ask often :P ). I'm happy to put you in touch with them if you'd like; see my email in my HN profile (and this invitation goes for anyone else out there using Rust in production capacities, of course!).
So MSFT uses Rust. :) That's actually quite a newsworthy thing, could be a lot more newsworthy if we knew the purpose it was used for was some mission critical component that also needs to be blazing fast.
Looking at Rust's strengths, and that MSFT has languages/compilers of it's own, the use case is prolly "mission critical component that also needs to be blazing fast". But for now we're guessing.
I hear you. At the same time, the particular project they're doing is an implementation of an open standard, to provide an alternative and prevent monoculture, so seems good to me. I'm not involved in the container space, so I can't speak to the quality, but that's what it looks like from here.
