---When this function is first called, the appropriate handler will be called for each installed server.
---When a new server is installed, the appropriate handler for that server will be called (this allows you for example to set up-new servers without restarting Neovim).

---```lua
--- require("mason-lspconfig").setup_handlers {

--- require("lspconfig")[server_name].setup {}

--- ["rust_analyzer"] = function ()
