Is anyone able to lay out some of the reasons why you might want to write web applications in rust? I was under the impression rust was designed as a safer language for low level systems programming. Thanks!

So, Futures are moving into the standard library; there’s been a last minute procedural issue over one name, and then they’ll be in. So “futures 1.0” isn’t as important, the futures library mostly provides extra utilities, not the core of futures themselves. It’s likely this means they’ll be in 1.33, February 28 (if my math is right)

There are however a few open discussions around the futures/task/waker parts, from the other RFC. I just wrote down a list of the open points here: https://github.com/aturon/rfcs/pull/15#issuecomment-44549238...

It's a bit rough to work with still - the IDE support is still a work in progress (though improving) and there is a compile step with every iteration (incremental compilation has improved this too). Diesel is the main library for interacting with SQL databases, it wasn't async last time I used it, and a quick web search tells me it still isn't - this has been a BIG problem with Rust over the last year, as everyone wa…

I've never tried Rust or Rocket, but it appears to be gaining popularity, so I have the following questions for existing users: What's it like to work with? Do you prefer it to JS/PHP/Python for web related projects? Can you iterate on code quickly, or is there a compile step on every iteration? Are there stable libraries for interacting with MySQL/Redis/Postgres asynchronously? Is there good IDE support, for example…

You can also cause segfaults, the point I think is more that it is hard to do this instead of easy as it is in some languages, like C.
