}

A run of glyphs sharing one font and size — the paintable unit.

Fields

font_id: u16

Index into the registry that shaped the run.

size: f32

Em size in points.

text: String

The text the run was shaped from. Glyph ids alone do not spell anything, and the correspondence exists only in the shaper’s output.

source: String

What the author wrote, where a transform made that differ from what was shaped, and empty where the two are the same.

source_map: Vec<u32>

The offset in source of every byte boundary of text. Empty alongside source.

text_start: u32

Byte offset of text in the paragraph the glyphs’ clusters index.

origin: Option<SourceRange>

Where the run was written: the node it was shaped from and the bytes of that node’s own text it stands for. None for text no node was walked for: page furniture, an ornament.

pseudo_element: Option<NodeId>

The pseudo-element the run was cut from, where it was cut from one.

inline: Option<NodeId>

The innermost inline element the run came from: a link, an emphasis, a strong, a code span. None on the text of the paragraph itself.

lead: f32

Points of space before the run’s first glyph, from the leading edges of the inline boxes that open on it.

trail: f32

Points of space after its last glyph, from the trailing edges of the ones that close on it.

features: Features

The features the run was shaped with.

color: Color

What the run is painted in.

decoration: TextDecoration

What is drawn across it: the rules text-decoration asks for, each painted over the run’s own advance.

glyphs: Vec<ShapedGlyph>

The glyphs, in visual order.

advance: u32

Total advance of the run’s glyphs, in font units. What an inline box takes beside them is lead and trail, in points.

Implementations

impl ShapedRun

pub fn glyph_ranges(&self) -> Vec<Range<u32>>

The byte range in text each glyph stands for, in glyph order. A glyph covers its cluster up to the next cluster that starts later — which is how a ligature comes to span the characters it swallowed.
