Enum Element 

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

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

Variants

Text(Text)

Row(Row)

Column(Column)

Spacer(Spacer)

Line(Line)

Rect(Rect)

Table(Table)

Image(Image)

List(List)

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.
