Expand description

Cache entry for full layout (PerformLayout mode).

This is the single “final layout” slot. It includes child positions (relative to parent’s content-box) and overflow/scrollbar info.

Fields§

§available_size: LogicalSize

The available size that was provided as input.

§result_size: LogicalSize

The computed border-box size (output).

§content_size: LogicalSize

Content overflow size (for scrolling).

§child_positions: Vec<(usize, LogicalPosition)>

Child positions relative to parent’s content-box (NOT absolute).

§escaped_top_margin: Option<f32>

First child’s escaped top margin.

§escaped_bottom_margin: Option<f32>

Last child’s escaped bottom margin.

§scrollbar_info: ScrollbarRequirements

Scrollbar requirements for this node.
