For production ready, out of the gate, little config, extensive ecosystem, Rust isn't quite there. It will take much more to get many of the things that other languages/frameworks/libraries already provide that are well tested and stable. But the community is progressing surprisingly fast, so I don't think it'll be long before enough of the helper libraries are well tested and stable that building a web server wouldn't be much more difficult than other options. For just a web server, depending on what you're doing, the benefits of using Rust compared to say Node or Go are still, IMO, not a big list YET. One big thing for me is the Rust types system.
I'm working on a new project now where my web server will be Node, however much of my api and micro services/jobs will be in Rust. I expect it to go well, we'll see.
