layout::display_list::largest_contenful_paint_candidate_collector

Struct LargestContentfulPaintCandidateCollector

pub(crate) struct LargestContentfulPaintCandidateCollector {
    pub lcp_candidate: Option<LCPCandidate>,
    pub viewport_rect: LayoutRect,
    pub did_lcp_candidate_update: bool,
}

Fields§

§lcp_candidate: Option<LCPCandidate>

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

§viewport_rect: LayoutRect

The rect of viewport.

§did_lcp_candidate_update: bool

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