Struct Row 

pub struct Row { /* private fields */ }

Builds a horizontal measured layout; defaults to zero gap and Start alignment.

Children are positioned in insertion order, then painted in stable z order. Empty nodes consume no gap; declared points and lines still occupy a slot. A child’s existing transformed AABB supplies its size; its previous position is replaced by arrangement. Parent placement and opacity apply afterwards.

Implementations

impl Row

pub fn new() -> Self

Creates a horizontal layout builder.

pub fn gap(self, gap: f64) -> Self

Replaces finite spacing; negative spacing intentionally overlaps.

pub fn alignment(self, alignment: Alignment) -> Self

Replaces cross-axis alignment.

pub fn children<Child: Into<Node>>( self, children: impl IntoIterator<Item = Child>, ) -> Node

Captures children for deferred, bounded measurement and arrangement.

Trait Implementations

impl Clone for Row

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Row

impl Debug for Row

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Row

fn default() -> Self

Returns the “default value” for a type.
