Struct Line

Source

pub struct Line {
    pub glyph_start: usize,
    pub glyph_end: usize,
    pub metrics: LineMetrics,
}

Expand description

A single laid-out line: a contiguous slice of positioned glyphs plus its metrics.

Fields§

§glyph_start: usize

Index of the first glyph of this line in LayoutResult::glyphs.

§glyph_end: usize

Index past the last glyph of this line in LayoutResult::glyphs.

§metrics: LineMetrics

Vertical and width metrics for the line.

Implementations§

Source §

impl Line
