I love how fast Windsurf and Cursor are with the "tab-tab-tab" code auto-completion, where nearly everything suggested is spot-on and the suggestions keep on rolling, almost automating the entire task of refactoring for you. This form of autocomplete works really well with TypeScript and other scripting languages.
IntelliJ / RustRover never got anywhere close to that level of behavior you can get in Cursor and Windsurf, neither in conjunction with JetBrains own models or with Co-pilot. I chalked it up as an IDE / model / language mismatch thing. That Rust just wasn't amenable to this.
A few questions:
1) Are we to that magical tab-tab-tab and everything autocompletes fluently with Rust yet? (And does this work in Zed?)
2) How does Zed compare to Cursor and Windsurf? How does it compare to RustRover, and in particular, JetBrains' command of the Rust AST?
I think they all use LSP, so whether you use neovim or Zed there shouldn't be a difference? (not 100% sure, but that's my basic understanding of LSP).
RustRover has the best AST suggestions and refactoring support out there. It works in gigantic workspaces, across build scripts, proc macros, and dynamic dispatch.
The problem with RustRover has been the lackluster AI support. I've been finding AI autocomplete generally much more useful than AST understanding, though having both would be killer.
Every time I've encountered a vim emulator I've found it is just close enough that my fingers are doing the wrong things so often it's frustrating. Almost to the point where I would prefer a non-vimmy editor since at least then my fingers always do the wrong thing.
