Enum Element 

pub enum Element {
    Text(Text),
    Row(Row),
    Column(Column),
    Spacer(Spacer),
    Line(Line),
    Rect(Rect),
    Table(Table),
    Image(Image),
    List(List),
    TableOfContents(TableOfContents),
    PageBreak,
}

One element in the document tree. Enum-based (not Box<dyn Layoutable>) — a closed, small set of primitives.

serde (issue #17): internally tagged on a type field ({"type": "text", "content": "...", ...}), snake_case variant names. Image’s JSON shape is base64 (see its own doc comment), not the same fields its Rust builder exposes.

Variants

Text(Text)

Row(Row)

Column(Column)

Spacer(Spacer)

Line(Line)

Rect(Rect)

Table(Table)

Image(Image)

List(List)

TableOfContents(TableOfContents)

PageBreak

Forces a page break at this point in the enclosing flow, regardless of whether the remaining content would still fit (Phase 2).

Implementations

impl Element

pub fn common(&self) -> Option<&Common>

Shared style properties, where applicable. Spacer and PageBreak carry no Common (nothing to size/clip/keep-with-next).

pub fn common_mut(&mut self) -> Option<&mut Common>

Mutable counterpart to Self::common — used by List’s layout translation to make item content fill the remaining row width (flex(1.0)) without needing a bespoke setter per element variant.
