Positioned, resolved layout output ready for the facade to translate into lightweight-pdf-writer content-stream operations. Never seen by lightweight-pdf-writer directly (plan/00a-contracts-and-artifacts.md point 3).

Variants

Empty

TextLines

Already-wrapped lines, one per output line, top-aligned within area.

Fields

area: Rect

style: TextStyle

lines: Vec<String>

line_height_pt: f32

Rect

Fields

area: Rect

background: Option<Color>

border: Option<Border>

Line

Fields

x1: f32

y1: f32

x2: f32

y2: f32

thickness: f32

color: Color

Image

A validated JPEG/PNG placed at its final, Contain-fit size. bytes are the original file bytes (facade decides how to embed them — JPEG passes through as DCTDecode, PNG gets decoded once here to split out the alpha channel as a SMask).

Fields

area: Rect

bytes: Arc<[u8]>

format: ImageFormat

width_px: u32

height_px: u32

components: u8

Group

A container’s own box: clipped (Grundprinzip 4), optionally painted with a background/border, holding its children.

Fields

area: Rect

clip: bool

background: Option<Color>

border: Option<Border>

children: Vec<RenderNode>

Implementations

impl RenderNode

pub fn clipped(area: Rect, inner: RenderNode) -> RenderNode

Wraps self in a clipping group bound to area — the render-pass safety net required from every element, not only containers (Grundprinzip 4/6).

pub fn height(&self) -> f32

Trait Implementations

impl Clone for RenderNode

fn clone(&self) -> RenderNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RenderNode

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

Formats the value using the given formatter.
