To clarify, author is https://github.com/popzxc, not me! My thoughts are here: https://matklad.github.io/2026/08/21/rust-glancer.html

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.

Thanks for drawing attention to this interesting topic!

Why don't people explain their acronyms? What is a Rust LSP?
francislavoie•56m ago
Language Server Protocol, it's what your IDE (like VSCode or other) uses to do linting, syntax checking, and "go to reference" stuff.
xixixao•56m ago
People communicate with regards to the audience they expect.

This 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.

It makes sense to always explain acronyms. I always do to avoid random people reaching out for more explanations

LSP is a well known term among programmers these days.

Not if an LLM writes your code. I get thousands of lines of high quality Rust per day without ever stepping into VScode.

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.

Does anyone have experience using that? Any tradeoffs?

LSP = language server protocol
