For web dev, the ecosystem isn't quite there yet. I've written a few utilities and toy APIs, but don't feel like the web ecosystem is was rich as it needs to be for a serious project. Actix comes close. A few others like Warp ND Gotham are interesting. I'm waiting for rocket to compile in stable, and pick up async.

But yes, rust is definitely pretty cool, and I'm annoyed that I finally "understand" the language on my nth attempt at learning it, and still haven't found a good use case for it.
