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 of line
line_w: f32
width of line
line_height: f32
height of this line
glyph_ascent: f32

Implementations§
source§impl<'a> LayoutRun<'a>
impl<'a> LayoutRun<'a>
sourcepub fn highlight(
&self,
cursor_start: Cursor,
cursor_end: Cursor
) -> Option<(f32, f32)>
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.
