LayoutView

pub(open) trait LayoutView {
  fn uid(Self) -> Int
  fn computed_x(Self) -> Double
  fn computed_y(Self) -> Double
  fn computed_width(Self) -> Double
  fn computed_height(Self) -> Double
  fn children(Self) -> Array[Self]
  fn text(Self) -> String?
  fn resource_state(Self) -> ResourceLoadState?
}

Read-only view of a computed layout tree node.

Implementations expose just the fields needed by external consumers (web vitals metrics, accessibility tree walks, etc.) without leaking layout-engine state. The layout engine's LayoutNode (in mizchi/crater-layout/tree) is the canonical implementation; tests and alternative engines can provide their own.

#
ResourceLoadState

source

pub(all) enum ResourceLoadState {
  Pending
  Resolved
  Error
}

Loading state of an intrinsic-sized resource (image, etc). Abstract view of layout-engine-specific resource tracking so that downstream consumers (web vitals, accessibility walks, ...) can reason about resource readiness without depending on the layout engine's internal state representation.
