Struct Size

pub struct Size {
    pub w: f32,
    pub h: f32,
}

Width and height in logical pixels.

Examples

use ailloli_ui_core::Size;
assert_eq!(Size::new(20.0, 10.0), Size { w: 20.0, h: 10.0 });

Fields

w: f32

Width in logical pixels.

h: f32

Height in logical pixels.

Implementations

impl Size

pub fn new(w: f32, h: f32) -> Self

Creates a size (w, h) without rejecting negative or non-finite values.

Examples

use ailloli_ui_core::Size;
assert_eq!(Size::new(20.0, 10.0).w, 20.0);

pub fn is_empty(&self) -> bool

Returns true when either dimension is zero or negative.

NaN is not classified as empty because comparisons with it are false.

Examples

use ailloli_ui_core::Size;
assert!(Size::new(0.0, 10.0).is_empty());

pub fn min(self, other: Self) -> Self

Returns the component-wise floating-point minimum.

Examples

use ailloli_ui_core::Size;
assert_eq!(Size::new(3.0, 8.0).min(Size::new(5.0, 4.0)), Size::new(3.0, 4.0));

pub fn max(self, other: Self) -> Self

Returns the component-wise floating-point maximum.

Examples

use ailloli_ui_core::Size;
assert_eq!(Size::new(3.0, 8.0).max(Size::new(5.0, 4.0)), Size::new(5.0, 8.0));

pub fn clamp(self, min: Self, max: Self) -> Self

Clamps each component between the corresponding inclusive bounds.

Panics

Panics if either interval is reversed or contains a NaN bound.

Examples

use ailloli_ui_core::Size;
assert_eq!(Size::new(20.0, 2.0).clamp(Size::new(4.0, 4.0), Size::new(10.0, 10.0)), Size::new(10.0, 4.0));

Trait Implementations

impl Clone for Size

fn clone(&self) -> Size

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Size

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

Formats the value using the given formatter.

impl Default for Size

fn default() -> Size

Returns the “default value” for a type.

impl PartialEq for Size

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