Struct PaintTimingHandler 

pub(crate) struct PaintTimingHandler {
    lcp_size: f32,
    lcp_candidate: Option<LCPCandidate>,
    viewport_rect: LayoutRect,
    lcp_candidate_updated: bool,
}

Fields

lcp_size: f32

The document’s largest contentful paint size

lcp_candidate: Option<LCPCandidate>

The LCP candidate, it may be a image or text.

viewport_rect: LayoutRect

The rect of viewport.

lcp_candidate_updated: bool

Flag to indicate if there is an update to LCP candidate. This is used to avoid sending duplicate LCP candidates to Paint.
