Enum SurfaceRole 

pub enum SurfaceRole {
    SectionCard,
    Window,
    Scrim,
}

Default navigation sidebar width (split presentation) until the pane reports its size. Semantic container surfaces (see ContainerProps::role): each backend maps a role to its own theme-adaptive material so the fill tracks light/dark mode without app code.

Variants

SectionCard

A form section card, the platform’s grouped-content background: AppKit quaternary system fill, libadwaita .card, Qt palette(alternate-base), UIKit tertiary system fill, Material surface-container, XAML card background brush.

Window

The window’s own background, the surface a page sits on: what an opaque cover paints by default, and the card of a composed modal sheet (docs/cover.md “Modal sheet”).

Scrim

The layer between a composed modal sheet and the page under it, which says the page is out of reach until the sheet goes. The container’s background is the plain dimming a backend draws when it has no material of its own; the web frosts the page instead.
