Struct TextLayout 

pub struct TextLayout {
    pub lines: Arc<[TextLine]>,
    pub metrics: TextMetrics,
    pub font_runs: Arc<[FontRunDebug]>,
    pub overflowed: bool,
    /* private fields */
}

Fields

lines: Arc<[TextLine]>

metrics: TextMetrics

font_runs: Arc<[FontRunDebug]>

overflowed: bool

Whether the source had content outside the retained layout’s visible bounds. Visible layouts deliberately leave this false.

Implementations

impl TextLayout

pub fn glyph_count(&self) -> usize

pub fn line_caret_positions(&self, line: usize) -> &[TextCaretPosition]

Returns the visual insertion points for one laid-out line in left-to-right screen order.

Trait Implementations

impl Clone for TextLayout

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TextLayout

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

Formats the value using the given formatter.

impl TextGeometry for TextLayout

fn metrics(&self) -> TextMetrics

fn line_count(&self) -> usize

fn get_line(&self, index: usize) -> Option<TextLineRef<'_>>

fn lines(&self) -> TextLines<'_>

fn lines_between(&self, top: f32, bottom: f32) -> TextLines<'_>

Lines that may meet the vertical span top..bottom, plus one line on each side; pad the span for glyphs that overhang their line.

fn line_for_offset(&self, byte: usize) -> usize

Index of the line whose [start, end) holds byte, or the last line when none does, like Flutter’s Paragraph.getLineBoundary.

fn line_caret_positions(&self, line: usize) -> &[TextCaretPosition]

The visual insertion points of one line in left-to-right screen order.

fn line(&self, index: usize) -> TextLineRef<'_>

The line at index.
