调研方向

Read the rust.vim configuration and formatting documentation to determine how rustfmt options are passed and whether .rustfmt.toml is discovered from a parent directory. The issue gives no file or test entry point, so first locate the documentation or code that handles rustfmt_options. Done means documenting a working setup that applies the stated imports_layout configuration.

描述

  • rust.vim version: Whatever comes automatically by including "rust-lang/rust.vim" in my plugins.lua file
  • nvchad distro of Neovim.

Steps to reproduce:

In my plugin directory I currently have:

  {
    "rust-lang/rust.vim",
    ft = "rust",
    init = function ()
      vim.rustfmt_options = "+nightly"
      vim.g.rustfmt_autosave = 1
    end
  },

This is working inasmuch as it's reformatting my code on save.

However, it's ignoring the configurations I have set in the .rustfmt.toml in the parent directory.

For example:

imports_layout = "Vertical"

should result in the imports being stacked, but the formatting from rust.vim is undoing that.

Expected vs. actual behavior:

This isn't a bug as much as a gap in my knowledge. I'd hope to find a solution that recognizes my .rustfmt.toml and includes the configuration. Perhaps I could include a lua script that checks if it exists and includes it in the rustfmt_options?
