Not a Rust developer, but this project sounds sexy to me! :)

I use Emacs as much as possible, but for Java dev use IntelliJ because the Java plugins I've tried were always relatively clunky. Having great language support regardless of editor sounds wonderful!

You can develop Rust with IntelliJ as well. There's a plugin out there.

I think he's saying he'd rather use Emacs for Java dev, but IntelliJ is a necessary evil. For Rust, there's https://github.com/racer-rust/emacs-racer which seems pretty solid.

P.S. Regarding Java dev on Emacs, ENSIME (http://ensime.github.io) now works with java-mode rather than only Scala. I use it for Android development, and it's not perfect but works well enough.

They gave it a snazzy site: https://intellij-rust.github.io/

One really interesting thing about this effort is that the IntelliJ folks have their own stuff for autocomplete; they're not using racer.

Yeah, that seems nearly a constant for them. For example, in ReSharper (and presumably Project Rider), despite C# having the excellent, very fast (and, critically, fully open source!) compiler-as-a-service, Roslyn, they continue to use their own internal compiler service for code autocompletion, refactoring, and correctness analysis.

Resharper has been in development far longer than Roslyn and seems to be much more suited to working with partially incorrect code (the kind you have while typing away) and incremental changes.

Does Roslyn have the same support?

Roslyn is built for incomplete/flawed code

Ah, excellent!

I guess JetBrains is heavily invested in ReSharper (and the underlying AST code) which would explain why they won't want to switch right away, if at all.
