Expand description

Read-only snapshot of a scroll node’s state, returned by CallbackInfo queries.

Provides all the information a timer callback needs to compute scroll physics without requiring mutable access to the ScrollManager.

§max_scroll_y: f32

Maximum scroll in Y direction

§overscroll_behavior_x: OverscrollBehavior

Per-node overscroll behavior for X axis

§overscroll_behavior_y: OverscrollBehavior
