Description

I am trying to setup my rust DAP. Before this I had configured rust_analyser in mason.lua.
It is showing constantly -

nvim-lspconfig.rust_analyzer has been setup.
This will likely lead to conflicts with the rustaceanvim LSP client.
See ':h rustaceanvim.mason'

As it said, I made this rustaceanvim.lua file to retain the configs in mason.lua and remove the warning -

return {
	"mrcjkb/rustaceanvim",
	version = "^5", -- Recommended
	lazy = false, -- This plugin is already lazy

	config = function()
		vim.g.rustaceanvim = {
			server = {
				cmd = function()
					local mason_registry = require("mason-registry")
					local ra_binary = mason_registry.is_installed("rust-analyzer")
							-- This may need to be tweaked, depending on the operating system.
							and mason_registry.get_package("rust-analyzer"):get_install_path() .. "/rust-analyzer"
						or "rust-analyzer"
					return { ra_binary } -- You can add args to the list, such as '--log-file'
				end,
			},
		}
	end,
}

But it is still not dissapearing.
I tried the below combinations- ( X means didnt work)

1. Above - X
2. removed any rust_analyser mentioned from mason lspconfig and added ABOVE - X
3. removed any rust_analyser... and only use the README.md mentioned 3 line rustaceanvim.lua - X

I donno what to do, I reinstalled rust-analyser just in case. Still didnt work. Please help me setup LSP and DAP for Rust!

Example Code

I am putting links to my [mason.lua](https://github.com/AnirudhG07/dotfiles/blob/ugcl/nvim/.config/nvim/lua/anirudh/plugins/lsp/mason.lua), [lspconfig.lua](https://github.com/AnirudhG07/dotfiles/blob/ugcl/nvim/.config/nvim/lua/anirudh/plugins/lsp/lspconfig.lua) and [rustaceanvim.lua](https://github.com/AnirudhG07/dotfiles/blob/ugcl/nvim/.config/nvim/lua/anirudh/plugins/rustaceanvim.lua) file. Please suggest changes based on them. I have no clue what to do.
It would be appreciated for some improvements to rustaceanvim.lua file!
