Struct Line 

pub struct Line {
    pub runs: Vec<ShapedRun>,
    pub spans: Spans,
    pub boxes: Vec<InlineFragment>,
    pub width: u32,
    pub overhang: f32,
    pub protrusion: f32,
    pub box_: LineBox,
}

One typeset line: shaped runs plus its width in font units.

A line is a band of the page, which is set in one span or in several. The runs are in reading order across all of them.

Fields

runs: Vec<ShapedRun>

The line’s runs, in visual order.

spans: Spans

The spans the runs are divided between, in reading order.

boxes: Vec<InlineFragment>

The boxes the inline elements on the line paint there, outermost first. Empty on the ordinary line of a book.

width: u32

Advance of the line’s glyphs, trailing spaces excluded; a hyphenated line’s hyphen is charged here even though the glyph joins the runs when the structured outpur paints it. What hangs past the measure is charged here too, and taken off again by overhang and protrusion.

overhang: f32

Points the line’s last glyph hangs past the measure.

protrusion: f32

Points the line’s first glyph hangs before the line’s origin.

box_: LineBox

The line’s vertical geometry — computed here, in points; downstream stages position against it, never re-measure.

Implementations

impl Line

pub fn of(runs: Vec<ShapedRun>, box_: LineBox) -> Line

Shaped runs as a line of one span: page furniture, an ornament, an initial letter, and anything else set rather than broken.
