Feature description

For larger projects rust-analyzer takes a long time to load. I fully understand that this is not the fault of this plugin, but rust-analyzer itself. One band-aid that could help with this plugin though is to start up the lsp client immediately on opening the workspace to get the rust-analyzer timer started ASAP. It would be nice to have a config option where that is possible.

For my specific use case I would check the first level of CWD for a cargo.toml and conditionally start the lsp client automatically if it exists.

This could be done using :RustAnalyzer start but it looks like this command is unavailable until after the first rust file attach. (Unsure if that is a bug or intended behavior)

I don't think Neovim's LSP client lets you start a server without a buffer to attach to (vim.lsp.start attaches to the current buffer if you don't specify one).

I'd recommend ra-multiplex. You still have the initial startup time, but it keeps rust-analyzer running between sessions. Rustaceanvim auto-detects a running ra-multiplex server and connects to it for you.

I'll look into this. Thanks!
