Struct TextLayoutData 

Source 
pub struct TextLayoutData {
    pub width: f32,
    pub height: f32,
    pub line_height: f32,

Expand description

Cached text layout result with pre-computed glyph positions.

Compute once during measure(), reuse for:

  • Cursor X position rendering
  • Selection highlight geometry
  • Click-to-position cursor

Fields§

§width: f32

Total width of laid out text

§height: f32

Total height of laid out text

§line_height: f32

Height of a single line

§glyph_x_positions: Vec<f32>

X position at each character boundary (including end)

§char_to_byte: Vec<usize>

Byte offset for each character index

§lines: Vec<LineLayout>

Line layout information

§glyph_layouts: Vec<GlyphLayout>

Visual glyph boxes in shaped order.
