Struct ResolvedLayout

pub struct ResolvedLayout {
    pub width: Option<f32>,
    pub height: Option<f32>,
    pub min_width: Option<f32>,
    pub max_width: Option<f32>,
    pub min_height: Option<f32>,
    pub max_height: Option<f32>,
}

Resolved explicit sizes from LayoutStyle (fill / px / percent).

None on an axis means intrinsic sizing (children sum, text measure, etc.).

Examples

use ailloli_ui_core::{Constraints, Size};
use ailloli_ui_core::style::{LayoutStyle, resolve_widget_size};
let size = resolve_widget_size(Size::new(20.0, 10.0), LayoutStyle::new().width(40.0), Constraints::loose(100.0, 100.0));
assert_eq!(size, Size::new(40.0, 10.0));

Fields

width: Option<f32>

Explicit width in logical pixels, or None for intrinsic width.

height: Option<f32>

Explicit height in logical pixels, or None for intrinsic height.

min_width: Option<f32>

Resolved minimum width, or None when no minimum was specified.

max_width: Option<f32>

Resolved maximum width, or None when no maximum was specified.

min_height: Option<f32>

Resolved minimum height, or None when no minimum was specified.

max_height: Option<f32>

Resolved maximum height, or None when no maximum was specified.

Implementations

impl ResolvedLayout

pub fn size( self, intrinsic_w: f32, intrinsic_h: f32, parent: Constraints, ) -> (f32, f32)

Combines intrinsic size with explicit axes and min/max bounds under parent.

Per-widget minimums are applied before maximums. An explicit axis is clamped to the ordered parent interval; an intrinsic axis is capped only at the parent maximum and is not expanded to the parent minimum.

Panics

May panic when an explicit axis is clamped against parent bounds that remain NaN after ordering.

Examples

use ailloli_ui_core::Constraints;
use ailloli_ui_core::style::ResolvedLayout;
let resolved = ResolvedLayout { width: Some(40.0), ..ResolvedLayout::default() };
assert_eq!(resolved.size(10.0, 20.0, Constraints::loose(100.0, 100.0)), (40.0, 20.0));

Trait Implementations

impl Clone for ResolvedLayout

fn clone(&self) -> ResolvedLayout

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResolvedLayout

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

Formats the value using the given formatter.

impl Default for ResolvedLayout

fn default() -> ResolvedLayout

Returns the “default value” for a type.

impl PartialEq for ResolvedLayout

fn eq(&self, other: &ResolvedLayout) -> 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.
