Struct TextDrawParams

    pub rect: Rect,

    pub layout: TextLayout,
    pub color: Color,
    pub text_style: Arc<TextStyle>,

}

A DrawScope text run, lowered into the vocabulary the text pipeline already speaks.

The fields line up one-for-one with CompositorScene::push_text in both backends, so a text primitive joins the same glyph atlas, run cache and shader the Text composable uses instead of getting a pipeline of its own.

Fields

rect: Rect

Layer-transformed block box. Glyphs are laid out from its top-left; the draw scope already resolved alignment into it.

text: Rc<AnnotatedString>

The text to draw.

layout: TextLayout

The lines and glyphs, from rect’s top left corner.

color: Color

Color that fills the glyphs.

text_style: Arc<TextStyle>

Style the text is drawn with.

style_hash: u64

text_style’s render hash.

font_size: f32

Font size in logical pixels, before scale is applied.

scale: f32

Uniform layer scale — the factor glyphs are rasterized at.

clip: Option<Rect>

Clip rectangle that cuts the text, or None when nothing clips it.
