Your thoughts are quite cool! but I thought featuring the project itself would make more sense for a frontpage thread, so I'm going to merge the comments (such as they are) from https://news.ycombinator.com/item?id=49392654 and add your link to the toptext above. Thanks for drawing attention to this topic!

Waiting for RA to build up the full in memory data structure for a large Rust workspace is so painful. Honestly, I'd just assumed that was the only way and didn't realize Rust Rover was different.
replyDoes anyone have experience using that? Any tradeoffs?

Why don't people explain their acronyms? What is a Rust LSP?

People communicate with regards to the audience they expect.
replyThis is why Rust (it’s a systems programming language) and LSP (the language server protocol invented by VS Code) are not explained in the article.
I am hoping I don’t have to define the words I used, but if in doubt, Google or ChatGPT are your friends.

Language Server Protocol, it's what your IDE (like VSCode or other) uses to do linting, syntax checking, and "go to reference" stuff.
