Struct Rail 

pub struct Rail { /* private fields */ }

Rail — a compact, always-icon-only vertical navigation strip.

Where a collapsed Sidebar is a temporary icon view of a labelled panel, a Rail is a permanent slim bar (think a VS Code activity bar or a Material navigation rail). Labels always live in hover tooltips. Items added after footer are pinned to the bottom of the rail.

let clicked = sc::Rail::new("rail")
    .selected(self.page)
    .show(ui, |r| {
        r.item(sc::IconKind::Home, "Home");        // 0
        r.item(sc::IconKind::Search, "Explore");   // 1
        r.footer();                                // pin the rest to the bottom
        r.item(sc::IconKind::Settings, "Settings"); // 2
    });
if let Some(i) = clicked { self.page = i; }
