Rust has been in development for almost a decade at this point; but the language changed significantly many times before 1.0. It's been one year since the 1.0 release, which is the language we know today as "Rust". All those older languages are dead and gone now. I'm actually doing a talk about the ACM's Applicative conference in NYC this year talking about the history of Rust.

This is one thing that's a little annoying to me. I know if I develop a Rust app today I can't leave it alone or it will decay horribly.

That was true prior to last year's 1.0 being released, but since then code no longer breaks, (in any major ways anyway, there's been some soundness fixes for the good of the language's future). Also, the Rust teams runs any potentially breaking changes against the crates at crates.io and they even sent fixes to existing crates in the past.

Except the tooling, could be better. A language like Rust will benefit from a rich IDE a lot. But still the language is great.

I really wish that Jetbrains had a Rust IDE. I love their Go, and Erlang plugins for IntelliJ, Java with IntelliJ, and Clion with C. Without them, I don't think I could be anywhere as effective as I am. I tried to pickup Rust, but I was super frustrated by the code/compile/run cycle with the current plugin. But, hopefully more users will make that better.

Hey HN, do you knoe Any notable projects or startups using Rust? Web, desktop apps, scientific or algorithmic computing etc?

The most notable Rust project I know of is servo, the browser written in Rust.

https://github.com/servo/servo

It is a massive undertaking and it's already sort of working in many regards.

One year since stable? It feels like five years for the level of maturity they have achieved.

Replied in the wrong child.... May want to give VS Code + RustyCode[1] extensions a look.

I actually find the tooling to be quite decent. VSCode + Racer has worked pretty well for me so far.

I'd say rustdoc is pretty rough. It's very hard to navigate the rust stdlib vs, say, Go, and when you do find what you want, it's often specified in some very cryptic manner that seems to require a PL PhD.

It is a really big barrier to adoption because it's very hard to find out what functionality is or is not offered. Here's an example: I want to iterate over a set. Easy, right?

No.

http://static.rust-lang.org/doc/master/std/collections/hash_...

Look at the signature for Cycle. It's really hard to know what this does even though it's trivial:

fn cycle(self) -> Cycle where Self: Clone

When you click through to the real documentation, it describes a useful use case for this. But that's not how programmers think. They think "I need to do X right now so I'll find something that looks right" not "I'm going to click through the documentation... oh X looks interesting I'll remember that later". There's no way to infer what Cycle really does without having actually clicked through or used it.

If you (or anyone really) has specific thoughts here, that'd be super great. Rustdoc's output could use a lot of love, but we haven't figured out exactly what we want to do with it. And having worked with it daily for a few years now, I'm personally a bit blind to its shortcomings.

There is unofficial plugin: https://github.com/intellij-rust/intellij-rust and works very well: https://www.youtube.com/watch?v=mHa7QlFz7io (small video recorded by me)

I'd say the tooling is pretty great only with the exception of an IDE. Debugging, building, testing, packaging all seems pretty well handled.

Eh, debugging is a mess, at least on OS X. Rust advertises LLDB support, but it seems semi-broken. Listing source is non-functional and just setting a break-point requires a lot of hand-holding.
