Struct SurfaceId 

pub struct SurfaceId(/* private fields */);

A process-global, monotonically increasing identifier for one surface instance — a Tray, ContextMenu, or Popup — so a MenuEvent consumer can tell which surface an activation came from (issue #51).

Assigned once, in the surface’s constructor, from a process-wide AtomicU64 counter; every live surface has a distinct id, and ids are issued in creation order.
