Top 15 Rust Lsp Projects

lsp-ai
LSP-AI is an open-source language server that serves as a backend for AI-powered functionality, designed to assist and empower software engineers, not replace them.
Unless something's changed, every AI-backed language server I've tried in Helix suffers from the same limitation when it comes to completions: Suggestions aren't shown until the last language server has responded or timed-out. Your slowest language server determines how long you'll be waiting.
The only project I know of that recognizes this is https://github.com/SilasMarvin/lsp-ai, which pivoted away from completions to chat interactions via code actions.

Project mention: Show HN: Daily-notes.nvim – fuzzy time journal and planning plugin | news.ycombinator.com | 2025-02-08
The PKM space for neovim plugins is a surprisingly deep rabbithole but it can take quite a while to find what you need.
For completions and tagging https://github.com/Feel-ix-343/markdown-oxide works well for me and does pretty much everything I need.
There are also a glut of all-in-one solutions like https://github.com/nvim-neorg/neorg (org-mode for neovim) and https://github.com/epwalsh/obsidian.nvim.
Graphing is a bit harder because it doesn't intuitively match up with nvim's interface, but I'm pretty sure I saw something on Reddit the other day.

Project mention: So, you want to set up a Monaco editor with a language server | dev.to | 2024-10-19
There are other ways to run Language Server, e.g. one can create a new language server or a wrapper for existing one with pygls, to run it as Python process providing websocket server. Here is a great guide with introduction to language servers and monaco language client. Other similar option but for Rust is tower-lsp.
