Struct ResolvedParagraphLayout 

pub struct ResolvedParagraphLayout {
    pub constraint_width: Option<LayoutUnit>,
    pub size: LayoutSize,
    pub lines: Vec<LineMetric>,
    pub inline_boxes: Vec<RichTextInlineBox>,
    pub clusters: Vec<ParagraphCluster>,
    pub glyphs: Vec<ParagraphGlyph>,
    pub caret_stops: Vec<ParagraphCaretStop>,
    pub selection_boxes: Vec<ParagraphSelectionBox>,
}

Immutable, backend-neutral summary of one resolved paragraph.

The width is the exact wrapping constraint. Layout snapshots retain this result so paint, hit testing, caret/selection geometry, accessibility, and IME positioning can consume the same paragraph decision rather than derive another width from an ancestor.

Fields

constraint_width: Option<LayoutUnit>

size: LayoutSize

lines: Vec<LineMetric>

inline_boxes: Vec<RichTextInlineBox>

clusters: Vec<ParagraphCluster>

Visual-order glyph/cluster mapping used by hit testing and selection.

glyphs: Vec<ParagraphGlyph>

Shaped glyph positions mapped back to entries in clusters.

caret_stops: Vec<ParagraphCaretStop>

Legal caret positions, including bidi-affinity alternatives.

selection_boxes: Vec<ParagraphSelectionBox>

Atomic boxes from which arbitrary selection geometry is formed.

Implementations

impl ResolvedParagraphLayout

pub fn empty(constraint_width: Option<LayoutUnit>) -> Self

pub fn hit_test(&self, point: LayoutPoint) -> usize

Resolve a point to the nearest shaped cluster boundary.

pub fn caret(&self, index: usize, upstream: bool) -> Option<ParagraphCaretStop>

Return the resolved caret geometry for a byte index and affinity.

pub fn selection_rects(&self, start: usize, end: usize) -> Vec<LayoutRect>

Return visual rectangles for a logical byte range. Disjoint rectangles are preserved for bidi text; adjacent clusters on one line are merged.
