Struct TextLayoutResult 

pub struct TextLayoutResult {
    pub line_count: usize,
    pub width_px: f32,
    pub height_px: f32,
    pub first_baseline: f32,
    pub last_baseline: f32,
    pub did_overflow_width: bool,
    pub did_overflow_height: bool,
    pub lines: Vec<TextLineInfo>,
}

Result of text layout computation, provided to the on_text_layout callback. Exposes key information about the rendered text layout.

Fields

line_count: usize

Number of visual lines in the layout.

width_px: f32

Total content width in px.

height_px: f32

Total content height in px.

first_baseline: f32

First baseline position in px.

last_baseline: f32

Last baseline position in px.

did_overflow_width: bool

Whether text overflows the available width.

did_overflow_height: bool

Whether text overflows the available height.

lines: Vec<TextLineInfo>

Per-line layout information.
