Expand description

State for the segment grid visualization.

This struct manages the layout tree and scroll state for displaying segments in a grid view. The segment tree is lazily computed on first render and cached for subsequent frames.

Fields§

§segment_tree: Option<(TaffyTree<()>, NodeId, HashMap<NodeId, NodeContents>)>

The computed layout tree for the segment grid, or None if not yet computed.

Contains the taffy layout tree, root node ID, and a map of node contents.

§horizontal_scroll_state: ScrollbarState

State for the horizontal scrollbar widget.

§vertical_scroll_state: ScrollbarState

State for the vertical scrollbar widget.

§vertical_scroll: usize

Current vertical scroll position in pixels.

§horizontal_scroll: usize

Current horizontal scroll position in pixels.

§max_horizontal_scroll: usize

Maximum horizontal scroll position.

§max_vertical_scroll: usize

Maximum vertical scroll position.
