Function stack 

Source 
pub fn stack<I, E>(children: I) -> El
where
    I: IntoIterator<Item = E>,
    E: Into<El>,
Expand description

An overlay stack; children share the parent’s rect.

For modals, sheets, popovers, and tooltips reach for the named widget instead — dialog, sheet, popover, .tooltip(...). stack is the layered-visuals primitive (focus rings, custom badges painted over content) that those widgets compose against.
