glyphs: &'a [LayoutGlyph]

The array of layout glyphs to draw

max_ascent: f32

Maximum ascent of the glyphs in line

max_descent: f32

Maximum descent of the glyphs in line

line_y: f32

Y offset to baseline of line

line_top: f32

Y offset to top of line

Implementations

impl LayoutRun<'_>

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.

pub fn cursor_from_glyph_right(&self, glyph: &LayoutGlyph) -> Cursor

Trait Implementations

impl<'a> Debug for LayoutRun<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
