Struct FlowLayout 

pub struct FlowLayout {
    pub spacing: f64,
    pub run_spacing: f64,
    pub align: CrossAlign,
    pub uniform: bool,
}

A wrapping row (docs/size-classes.md “Adaptive pieces”): children keep their natural measure and lay out leading-to-trailing, breaking onto a new line where the next child would overflow the proposed width. Wrapping replaces main-axis negotiation, so flex is inert here: nothing grows, and a spacer() contributes nothing. RTL mirroring comes from place_child, the same as every layout.

Fields

spacing: f64

run_spacing: f64

Vertical gap between lines.

align: CrossAlign

How children align within their own line (a line is as tall as its tallest child).

uniform: bool

Uniform columns (RowFit::WrapColumns): every cell takes the widest child’s width and each line holds as many as the available width fits, so the wrapped lines align into columns; when any child grows (grow_w), the columns stretch to share the whole width. false packs each line at natural widths, which comes out ragged.

Trait Implementations

impl Layout for FlowLayout

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.
