Struct ChildLayout

pub struct ChildLayout {
    pub offset: Offset,
    pub size: Size,
    pub paint_bounds: Rect,
    pub visual_bounds: Rect,
}

Geometry assigned to one direct child by its parent.

All coordinates and dimensions are logical pixels. offset is relative to the parent, while both bounds are expressed in that same parent-local space. Values are stored verbatim; this type does not reject negative or non-finite geometry.

Examples

use ailloli_ui_core::{Offset, Rect, Size};
use ailloli_ui_runtime::layout::ChildLayout;

let child = ChildLayout {
    offset: Offset::new(4.0, 6.0),
    size: Size::new(20.0, 10.0),
    paint_bounds: Rect::new(4.0, 6.0, 20.0, 10.0),
    visual_bounds: Rect::new(3.0, 5.0, 22.0, 12.0),
};
assert_eq!(child.offset.x, 4.0);

Fields

offset: Offset

Child origin relative to the parent, in logical pixels.

size: Size

Measured child size in logical pixels.

paint_bounds: Rect

Region the child can paint, expressed in parent-local coordinates.

visual_bounds: Rect

Region containing the child’s visual effects, in parent-local coordinates.

Trait Implementations

impl Clone for ChildLayout

fn clone(&self) -> ChildLayout

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChildLayout

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

Formats the value using the given formatter.

impl PartialEq for ChildLayout

fn eq(&self, other: &ChildLayout) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
