Function open 

pub fn open<C, K, V>(
    choices: impl IntoIterator<Item = C> + Debug,
    opts: &(impl IntoIterator<Item = (K, V)> + Debug + Clone),
    callback: impl Fn(usize) + 'static,
    maybe_quickfix: Option<QuickfixConfig>,
) -> Result<()>
where
    C: Display,
    K: IntoLua,
    V: IntoLua,

Prompts the user to select an item from a list using Nvim’s vim.ui.select.

Wraps the Lua vim.ui.select function to provide an interactive selection prompt. The selected index (0-based) is passed to the provided callback. If a quickfix configuration is provided, an additional synthetic choice is added to open the quickfix list instead.

Errors

• Fails if vim.ui.select cannot be fetched from Lua globals.
• Fails if the options table cannot be created.
• Fails if calling vim.ui.select encounters an error.
