§text: &'a str

The original text line

§rtl: bool

True if the original paragraph direction is RTL

§glyphs: &'a [LayoutGlyph]

The array of layout glyphs to draw

§line_y: f32

Y offset to baseline of line

§line_top: f32

Y offset to top of line

§line_height: f32

Y offset to next line

§line_w: f32

Width of line

Implementations§

source§

impl<'a> LayoutRun<'a>

source

pub fn highlight( &self, cursor_start: Cursor, cursor_end: Cursor, ) -> Option<(f32, f32)>

Return the pixel span Some((x_left, x_width)) of the highlighted area between cursor_start and cursor_end within this run, or None if the cursor range does not intersect this run. This may return widths of zero if cursor_start == cursor_end, if the run is empty, or if the region’s left start boundary is the same as the cursor’s end boundary or vice versa.
