Span

Struct Span

pub struct Span {
    pub origin: f32,
    pub width: f32,
    pub ends_band: bool,
}

Expand description

One place a line may start and how wide it may run.

A band of the page is set in one span or in several, and a band set in several is still one line: the text crosses from span to span in reading order, and only the last of them ends where a line ends.

Fields§

§origin: f32

Points from the block’s leading edge the span starts at.

§width: f32

Points the span runs.

§ends_band: bool

Whether the band ends here.

Implementations§

impl Span

pub fn band(origin: f32, width: f32) -> Span

A span that is a band on its own.

pub fn ending(end: f32, width: f32) -> Span

A band width wide ending where a band of end points ends. A first-line indent and a drop cap beside the line both leave one: the line is shortened at its start.
