Many of the features of such crates are making their way to the standard library, so things will definitely improve. Figuring out what is best has taken some time and Rust has not …

Nope, try blocks are a new (unstable) feature

My point is that there or may or may not be reasonable justification for adding GATs, reasonable people can disagree on that. But async methods are not part of that justification. …

To be clear, there are not use cases in the std lib. The use case is as an intermediate representation for the compiler, and that is no motivation for inclusion in the language (in…

No, they're not. GATs are used internally in the compiler to implement async methods, but there is absolutely no need for them to be in the language for that (just like generators …

We'd like anyone who is interested in Rust to fill out the survey, even if you've stopped using Rust or have never used Rust (and of course if you're a Rust user, however much or l…

I'm sorry you've had that experience. We are working hard to be better open source citizens in many ways, including better communication on issues, etc.

This should work (it's my goto test case). You have to put the cursor in the erroring code to see the possible fix icon in the margin. If you don't see it please file an issue with…

We're literally hacking on this right now. It should be part of the early June stable release.

It should yes, if it doesn't then its a bug that I should fix...

Syntax highlighting is (usually) done by the editor, not the server in the LS protocol. The changes sent from editor to server are pretty minimal, and so the whole thing is pretty …

Indeed, the RLS uses that protocol to communicate with IDEs.

The compiler will not enforce more style in the future, that will be done by Rustfmt, a separate and optional tool. In fact, it is likely that the compiler lints which enforce styl…

Major points: donations are used for projects working on things like web literacy, rather than on large engineering projects like Firefox. The more Mozilla get from donations, the …

There is syntax highlighting for Vim, Emacs, and Sublime Text editors. GitHub does syntax highlighting for Rust repos and in Gists. There is support for Rust in the Pygments syntax…

With structs, pretty much the only difference is the syntax. Enums are probably where the biggest differences are from C, as far as data types go.

In Rust, we are quite strict about the syntax used for destructuring matching the syntax used for instantiation. There is a name in the tuple-struct declaration, therefore you must…

Featherweight Java ( http://www.fos.kuis.kyoto-u.ac.jp/~igarashi/papers/fj.html ) was a seminal paper which showed type soundness for Java. The formal syntax was a subset of Java s…

All array indexing is bounds checked, so those kind of errors are prevented. We're still working on the story around overflow checking

I actually used enumerate in an earlier version of this post, but in the case I used it didn't work (pointed out to me on /r/rust). I'm going to go into enumerate and other iterato…

It was a design decision made long ago and seems to have stuck (although is slightly less extreme than it used to be). I also used to hate the abbreviation, but I find you get used…
