Possibility of setting init_options for rust_analyzer

[tvsfx]

As a hack(?) to make range formatting work, I had to set rustfmt.rangeFormatting.enable = true both in init_options and settings in lspconfig. Concretely, my rust_analyzer config looks as follows:

  rust_analyzer = {
      init_options = {
          -- NOTE: for some reason, this has to be set at startup...
          rustfmt = {
              rangeFormatting = {
                  enable = true,
              },
          },
      },
      settings = {
          ...
          rustfmt = {
              rangeFormatting = {
                  enable = true,
              },
          },
          ... 
     }
}

I am looking into migrating to rustaceanvim and can see that there is a default_settings option, that allows me to set my current settings. However, I am seeing no such equivalent for the init_options key. Is there a way to set init_options when launching the LSP through rustaceanvim?

Hey 👋

You can add an init_options table to the vim.g.rustaceanvim.server config.

Oh, I didn't realize that would just work; when I glanced over the code I couldn't find any processing of init_options, and since settings is renamed to default_settings in this table, I assumed that keys weren't just passed through, but I guess other keys are.

This in combination with #49 should suffice then to port my current rust-analyzer setup; thanks!

Yep, it wasn't documented 😅
default_settings is just so you can override them with a .vscode/settings.json (which wouldn't be possible if you set settings directly.
