Struct LayoutDom 

pub struct LayoutDom {
    pub pages: Vec<LayoutPage>,
}

The output of the layout engine: positioned rectangles on pages.

Fields

pages: Vec<LayoutPage>

Laid out pages.

Implementations

impl LayoutDom

pub fn estimated_heap_bytes(&self) -> usize

Estimate the total heap bytes consumed by this layout tree.

Walks every page and every node recursively, summing the heap contributions of Vec fields (children, display_items, save_items) and inline String fields (name, content strings). The estimate is a lower bound — it does not account for Vec capacity overheads or internal allocator padding.

Primary use: memory-usage regression tests and profiling dashboards.

Trait Implementations

impl Debug for LayoutDom

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
