Feature description

I am troubleshooting an issue that I am unsure what the root cause is, to bisect the problem I would like to know the exact config that is being passed to RA when rustaceanvim calls it. I see that there is a :RustAnalyzer config command, but I am hoping for something more like a :RustAnalyzer showConfig command or the like.

You can use :checkhealth vim.lsp or :lua =vim.lsp.get_clients().

As always, thanks for your quick response. As a followup, it seems like the .vscode/settings.json is not being loaded as expected. And :checkhealth rustaceanvim returns a clean bill of health.

Answered my own question, VSCode's particular flavor of json is not accepted by rustaceanvim (this one has comments in it). Which makes sense if rustaceanvim is following official json spec.

Yep, rustaceanvim uses vim.json.decode which uses cjson.
