Struct CoverLayout 

pub struct CoverLayout {
    pub size: Rc<RefCell<Option<Size>>>,
}

Fullscreen cover (docs/cover.md): the cover node occupies no space where it sits in the tree (its native surface is presented over the window, outside the parent’s bounds), and its content is laid out at the size the backend reported via Event::FrameChanged, the same native-owned-frame contract as NavLayout pages.

Fields

size: Rc<RefCell<Option<Size>>>

Trait Implementations

impl Layout for CoverLayout

fn measure( &self, _cx: &mut dyn LayoutOps, _children: &[RNode], _p: Proposal, ) -> Size

fn place(&self, cx: &mut dyn LayoutOps, children: &[RNode], _bounds: Rect)

fn baseline( &self, _cx: &mut dyn LayoutOps, _children: &[RNode], _size: Size, ) -> Option<f64>

Where this node’s own first text baseline falls, measured from the top of a box of size (docs/baseline.md). None (the default) means the node has no baseline to offer, so a baseline-aligned parent falls back to box alignment for it.
