Struct OverlayLayout 

pub struct OverlayLayout { /* private fields */ }

Layout used by Overlay to keep the base child’s size authoritative while still allowing aligned overlay content.

Implementations

impl OverlayLayout

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

Sets the Alignment used to position overlay layers relative to the base.

pub const fn alignment_ref(&self) -> Alignment

Returns the current alignment.

Trait Implementations

impl Clone for OverlayLayout

fn clone(&self) -> OverlayLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OverlayLayout

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

Formats the value using the given formatter.

impl Default for OverlayLayout

fn default() -> OverlayLayout

Returns the “default value” for a type.

impl Layout for OverlayLayout

fn stretch_axis(&self) -> StretchAxis

Overlay stretches in both directions, allowing the base child to fill available space. The actual size is determined by the base child in size_that_fits.

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.
