Ask HN: Editor with the Best Rust Integration?

The Rust docs don't advertise a single recommended editor; they list VSCode, Sublime 3, Atom, IntelliJ IDEA, Eclipse, Vim, Emacs, and Geany, pretty much all in the same breath. I've been using VSCode so far and it's... okay. The Rust Language Server is pretty lacking compared to, say, the TypeScript one.

What does your Rust workflow look like? Is there an editor that has first-class Rust support yet?
