Struct DomTree 

pub struct DomTree {
    pub root: AriaNode,
    pub selectors: Vec<String>,
    pub iframe_indices: Vec<usize>,
}

Represents the ARIA snapshot of a web page Based on Playwright’s AriaSnapshot structure

Fields

root: AriaNode

Root AriaNode (usually a fragment)

selectors: Vec<String>

Array of CSS selectors indexed by element index

iframe_indices: Vec<usize>

List of iframe indices (for multi-frame snapshots)
