fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl TextLayout for TextLayout

fn size(&self) -> Size

The total size of this TextLayout.

fn trailing_whitespace_width(&self) -> f64

The width of this layout, including the width of any trailing whitespace.

fn image_bounds(&self) -> Rect

Returns a Rect representing the bounding box of the glyphs in this layout, relative to the top-left of the layout object.

fn text(&self) -> &str

The text used to create this layout.

fn line_text(&self, line_number: usize) -> Option<&str>

Given a line number, return a reference to that line’s underlying string.

fn line_metric(&self, line_number: usize) -> Option<LineMetric>

Given a line number, return a reference to that line’s metrics, if the line exists.

fn line_count(&self) -> usize

Returns total number of lines in the text layout.

fn hit_test_point(&self, point: Point) -> HitTestPoint

Given a Point, return a HitTestPoint describing the corresponding text position.

fn hit_test_text_position(&self, idx: usize) -> HitTestPosition

Given a grapheme boundary in the string used to create this TextLayout, return a HitTestPosition object describing the location of that boundary within the layout.

fn rects_for_range(&self, range: impl RangeBounds<usize>) -> Vec<Rect, Global>
