I wouldn't describe any of the issues I've had as major. There have been several papercuts (some of which are resolved by the current release), and I'm honestly not a huge fan of the iron library that I've used. I think in general I really like having Rust's nudges towards correctness for backend web code, but I need to try using something like tokio or rocket.rs instead of iron before I make too broad of a claim about how it is to develop. I think iron is good for several things, but the current amount of documentation (and several other factors) would prevent me from recommending using it in a new project right now. I'm bullish on Rust for web development, but I think that stable custom_derive with 1.15 is just the start of improved ergonomics for it.
