Struct VStackLayout 

pub struct VStackLayout {
    pub alignment: HorizontalAlignment,
    pub spacing: Computed<f32>,
}

Layout engine shared by the public VStack view.

Fields

alignment: HorizontalAlignment

The horizontal alignment of children within the stack.

spacing: Computed<f32>

The spacing between children in the stack.

Trait Implementations

impl Clone for VStackLayout

fn clone(&self) -> VStackLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VStackLayout

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

Formats the value using the given formatter.

impl Default for VStackLayout

fn default() -> Self

Returns the “default value” for a type.

impl Layout for VStackLayout

fn stretch_axis(&self, children: &[StretchAxis]) -> StretchAxis

A VStack claims nothing of its own — a column of labels is content-sized, like SwiftUI’s, and a parent placing an undersized column centers it per its alignment. What it does claim is whatever its children claim: filling comes from children that ask for it (Spacer, greedy frames, Color), and the ask has to survive the trip up through every container between that child and whoever owns the space.

fn size_that_fits( &self, proposal: ProposalSize, children: &[&dyn SubView], ) -> Size

Calculate the size this layout wants given a proposal.

fn place(&self, bounds: Rect, children: &[&dyn SubView]) -> Vec<Rect>

Place children within the given bounds.

fn explicit_horizontal( &self, alignment: HorizontalAlignment, _bounds: Rect, children: &[PlacedSubview<'_>], ) -> Option<f32>

Returns an explicit horizontal guide for this container, if any.

fn explicit_vertical( &self, _alignment: VerticalAlignment, _bounds: Rect, _children: &[PlacedSubview<'_>], ) -> Option<f32>

Returns an explicit vertical guide for this container, if any.

fn explicit_horizontal_alignments(&self) -> Vec<HorizontalAlignment>

Returns the horizontal alignments this container may expose explicitly.

fn explicit_vertical_alignments(&self) -> Vec<VerticalAlignment>

Returns the vertical alignments this container may expose explicitly.
