I was looking forward to parallel front-end[4], but I have not seen any improvement for these small changes.

For example, intelephense can show diagnostics in real time, there is no need to save the file to get new diagnostics. But rust-analyzer, the language server for rust, can only update diagnostics after saving the file.

6. Rust Analyzer

The rust-analyzer readme suggests you go here for support request. But even there, you'll need to provide more details to get useful help.

For example: https://github.com/rust-lang/rust-analyzer/blob/master/docs/...

> If you create an LSP, it will work best in VS Code.

Any editor can work just as well as (or even better than) VS Code.

So, apparently the reason why rust-analyzer, the LSP server for Rust does not have persistent caching is because it would make "optimizing initial passes less important".

All I want to know is: Will it have a build configuration pulldown?

I am not a Rust dev. It surely looks great.

However, from what I understand it seems to supply just a parser separate from the Rust compiler (https://github.com/rust-lang/rust-analyzer/tree/master/crate...) trying to keep up with Rust‘s development. So, in principle, it could have been just another treesitter parser plugin, too.

So, again, the LSP framework does not directly provide any magical benefit over a static parsing framework. All the semantic analysis capabilities stem from a good parser.

Rust

You can absolutely get nvim and rust analyzer working together. I personally use this: https://github.com/fannheyward/coc-rust-analyzer

nvim plugin](https://github.com/neoclide/coc.nvim) together with the rust analyzer plugin. It's given me the most complete, useful experience developing in rust on nvim. I absolutely love it and can't recommend it enough.

I use https://github.com/neoclide/coc.nvim with https://github.com/fannheyward/coc-rust-analyzer and this default config: https://github.com/ithinuel/dotfiles/blob/main/.config/nvim/coc-settings.json#L2-L9

If you're using coc-rust-analyzer, did you try setting rust-analyzer.inlayHints.enable to false?

Using this plugin I have installed several extensions like coc-clangd and coc-rust-analyzer .

It works pretty well with coc-rust-analyzer actually. but I eventually found the file tree in VSCode very useful, also the debugging interface, so I use VSCode with the Vim plugin. It is the best of both worlds how I feel.

I would install coc.nvim and https://github.com/fannheyward/coc-rust-analyzer

Yeah sorry I thought you were saying to use the rust-analyzer vim plugin.

VIM users too! It is available as a language server extension for CoC, called coc-rust-analyzer and it works just as well as the VSCode version.
