-/// Creates a new [`keyed::Column`] with the given children.
+/// Creates a new [`keyed::Column`] from an iterator of elements.

+/// Keyed columns distribute content vertically while keeping continuity.

+/// # Example
+/// ```no_run
+/// # mod iced { pub mod widget { pub use iced_widget::*; } }
+/// # pub type State = ();
+/// # pub type Element<'a, Message> = iced_widget::core::Element<'a, Message, iced_widget::Theme, iced_widget::Renderer>;
+/// use iced::widget::{keyed_column, text};
+///
+/// enum Message {

+/// fn view(state: &State) -> Element<'_, Message> {
+///     keyed_column((0..=100).map(|i| {
+///         (i, text!("Item {i}").into())
+///     })).into()
