Struct SurfaceScaffold 

pub struct SurfaceScaffold { /* private fields */ }

A full-viewport scaffold that positions a panel against a screen edge, optionally dims the area behind it, and dismisses on a press outside the panel. It is the reusable body of a drawer/modal: a shell mounts it as the root of a full-screen layer-shell surface, and a windowed app can mount it in-tree as an in-window portal — both get the same positioning and dismiss behaviour.

Like other full-surface roots it (re)computes its own layout on WindowResized; the runner synthesizes an initial one on resume, so the scaffold is laid out before its first frame.

Implementations

impl SurfaceScaffold

pub fn new( placement: &SurfacePlacement, content: Box<dyn LayoutItem>, dismiss: Option<Rc<dyn Fn()>>, ) -> Result<Self, LayoutError>

pub fn animate_in(self) -> Self

pub fn animate(self, transition: SurfaceTransition) -> Self

Drives the scaffold from a transition the caller owns, so it can also send the surface back out — see SurfaceTransition::leave.
