Struct CellCenter 

pub struct CellCenter;

A recycled tree cell’s anchor layout (docs/tree.md): row content hugs its own height, so center it in the cell’s fixed row height; PassThrough pins it to the top, which reads as a misaligned row whenever the content is shorter than the row (a 16pt label in a 28pt row sat 6pt high). Width still fills; a content taller than the row clamps to it.

Trait Implementations

impl Layout for CellCenter

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.
