Struct LayoutLine

pub struct LayoutLine {
    pub runs: Vec<PositionedRun>,
    pub y: f32,
    pub ascent: f32,
    pub descent: f32,
    pub leading: f32,
    pub line_height: f32,
    pub width: f32,
    pub char_range: Range<usize>,
}

Fields§

§runs: Vec<PositionedRun>§y: f32

Baseline y relative to block top (set by block layout).

§ascent: f32§descent: f32§leading: f32§line_height: f32

Total line height: ascent + descent + leading.

§width: f32

Actual content width (sum of run advances).

§char_range: Range<usize>

Character range in the block’s text.

Implementations§

impl LayoutLine

pub fn x_for_offset(&self, offset: usize) -> f32

Find the x coordinate for a char offset within this line.

Builds the line’s caret stops (logical_offset, x) in visual order — direction-aware, so an RTL run’s caret for its lowest offset sits at its rightmost edge — then returns the x of the stop matching offset (nearest by offset if there’s no exact match).
