I think the consensus among Rustaceans is that using Rust for web development today is an...aggressive choice. Especially with async/await not yet stabilized. I think most of the people doing it either have very specific requirements (wasm experiments maybe) or do it because it's fun to be on the ground floor of a new thing.

That said, I find Rust very pleasant to use. I don't have to make as many defensive copies of things or reach for as many immutable data structures, because I have much stronger guarantees around what code is allowed to mutate what data. I'm a fan of static typing, and I really like that enun matches will fail to compile by default if you haven't handled all the cases. There's a lot of explicitness like that, and I find explicitness pleasant. But of course different people feel differently about that, and there's also the widely acknowledged learning curve for lifetimes and borrowing.

Rust web dev-- aggressive? I struggle more with relational data modeling and refactoring my early design decisions than I struggle with Rust for web dev. I am not happy that the futures I painfully walked over hot coals to make work will be easily replaced by async/await but that's on me for not waiting until some undisclosed time in 2019 for async/await to release.

If anyone likes to compare apples with oranges and benchmarking web frameworks, actix-web framework (optimised for benchmarking, naturally) is leading in many categories: https://www.techempower.com/benchmarks/#section=data-r17&hw=...

With actix-web, you can run asyncio and sync code in the same server. It lets you take full advantage of Rust's concurrency.

Glad I'm not the only one who was struggling with gigantic and confusing error messages that were fixed by trial and error (usually adding a `.map_err(|_| ())`).

Will actix-web become obsolete or be replaced when Rust releases async/await in 2019?

No; async/await produces Futures, which is what actix-web uses.

It will use a slightly older futures, but that's why there's a compatibility layer, and I'm sure they'll update fairly quickly after stabilization and so you could just use that version as well.
