Struct ZStack 

pub struct ZStack {
    pub id: Option<NodeId>,
    pub children: Vec<Node>,
}

A z-axis stacking container that layers children on top of each other.

Children are painted in order: the first child is at the bottom, the last is on top. Use Positioned children to place them at absolute offsets within the stack.

The stack’s size is determined by its largest child.

Example

ZStack {
    children: vec![
        Image { source: "bg.png".into(), ..Default::default() }.into_node().into(),
        Positioned {
            bottom: Some(16.0),
            right: Some(16.0),
            child: Some(Box::new(Text::new("Overlay").into_node())),
            ..Default::default()
        }.into_node().into(),
    ],
    ..Default::default()
}

Fields

id: Option<NodeId>

Explicit node identity.

children: Vec<Node>

Children painted in order (first = bottom, last = top).
