Top 7 Rust Lsp Projects

tower-lsp

3 570 3.4 Rust

Language Server Protocol implementation written in Rust

Project mention: State of the Ruby language server (LSP) ecosystem / looking for suggestions | reddit.com/r/ruby | 2022-10-02

I realize this might not be for everyone, but I'm writing it in Rust using Lib-ruby-parser and tower-lsp: two existing libraries that handle a bunch of the heavy lifting for me. I'm more productive in Rust than with Ruby at this point, despite doing Ruby full time for 15 years, plus I really really don't want to have to deal with a slow LSP--that was the whome impetus for this project. I started in the spring, made a bunch of headway, then backtracked to redo the internals to make it easier to handle monkeypatching, overriding/redefining of methods, etc. across your project.
typst-lsp

2 546 9.4 Rust

A brand-new language server for Typst, plus a VS Code extension

Project mention: Using sub-files imported into main file, while citing a single bibliography. | reddit.com/r/typst | 2023-04-21

Are you using the VSCode extension to render the pdf? If so I just filed an issue which may be the same problem you are facing. Have you tried using the command line interface instead? It should work with the CLI. https://github.com/nvarner/typst-lsp/issues/100

lapce-cpp-clangd

1 11 10.0 Rust

C/C++ LSP plugin based on clangd for Lapce

Project mention: Lapce - A modern open source code editor in Rust | reddit.com/r/programming | 2023-02-09

For language support. You need to install plugins. In this case, you need to install the clangd plugin https://github.com/lapce-community/lapce-cpp-clangd However, it might still not work for you because of your weird file extension policy. AFAIK, the language detection is hardcoded although this can be fixed I think quite easily I think.
