Struct HitTestSpatialNode 

Source 
struct HitTestSpatialNode {
    pipeline_id: PipelineId,
    world_content_transform: FastTransform<LayoutPixel, WorldPixel>,
    world_viewport_transform: FastTransform<LayoutPixel, WorldPixel>,
    external_scroll_offset: LayoutVector2D,
}
Expand description

A copy of important spatial node data to use during hit testing. This a copy of data from the SpatialTree that will persist as a new frame is under construction, allowing hit tests consistent with the currently rendered frame.

Fields§

§pipeline_id: PipelineId

The pipeline id of this node.

§world_content_transform: FastTransform<LayoutPixel, WorldPixel>

World transform for content transformed by this node.

§world_viewport_transform: FastTransform<LayoutPixel, WorldPixel>

World viewport transform for content transformed by this node.

§external_scroll_offset: LayoutVector2D

The accumulated external scroll offset for this spatial node.
