---@class Server
--@param opts table
-- @field name (string) The name of the LSP server. This MUST correspond with lspconfig's naming.
--
-- @field homepage (string) A URL to the homepage of this server. This is for example where users can
-- report issues and receive support.
--
-- @field installer (function) The function that installs the LSP (see the .installers module). The function signature should be `function (server, callback)`, where
-- `server` is the Server instance being installed, and `callback` is a function that must be called upon completion. The `callback` function
-- has the signature `function (success, result)`, where `success` is a boolean and `result` is of any type (similar to `pcall`).
--
-- @field default_options (table) The default options to be passed to lspconfig's .setup() function. Each server should provide at least the `cmd` field.
--
-- @field root_dir (string) The absolute path to the directory of the installation.
-- This MUST be a directory inside nvim-lsp-installer's designated root install directory inside stdpath("data"). Most servers will make use of server.get_server_root_path() to produce its root_dir path.
--
-- @field post_setup (function) An optional function to be executed after the setup function has been successfully called.
-- Use this to defer setting up server specific things until they're actually
-- needed, like custom commands.
--
-- @field pre_setup (function) An optional function to be executed prior to calling lspconfig's setup().
-- Use this to defer setting up server specific things until they're actually needed.
