Variants

IconProgress(Vec<(usize, Option<f64>)>)

Active icon overlays by row index: None spins, Some(0..=1) fills a circle. Rows absent from this complete snapshot have no overlay. Does not relayout rows. Currently rendered by AppKit/UIKit; other backends may ignore this decoration.

Selected(Option<usize>)

Programmatic highlight sync: toolkits apply without re-emitting SelectionChanged (the TextField from_native echo rule).

Items

The item set changed (data-driven nav().items(signal, …)): rebuild the rows from these labels/icons, then apply selected (docs/navigation.md). Applied without re-emitting SelectionChanged.

rows_changed is Some when the rows themselves are the ones already shown (same keys, sections and row menus) and only these rows’ title, icon, tint or badge moved: a count ticking, a language change. A backend updates those rows in place (a tab’s badge, a menu item’s title) rather than rebuilding, which on most platforms re-lays the bar and replays its selection animation; one that cannot rebuilds as for None.
