Struct PhysicalExtent

pub struct PhysicalExtent {
    pub width: u32,
    pub height: u32,
}

Physical pixel dimensions of a render destination.

This renderer-local type keeps presentation adapters such as winit or OpenXR outside the render-target contract. Hosts convert their native size type at the adapter boundary.

Examples

use ailloli_ui_render_wgpu::PhysicalExtent;
let extent = PhysicalExtent { width: 800, height: 600 };
assert_eq!(extent, PhysicalExtent::new(800, 600));

Fields

width: u32

Width in physical device pixels.

height: u32

Height in physical device pixels.

Implementations

impl PhysicalExtent

pub const fn new(width: u32, height: u32) -> Self

Creates an extent without clamping either axis.

Examples

use ailloli_ui_render_wgpu::PhysicalExtent;
let extent = PhysicalExtent::new(1920, 1080);
assert_eq!((extent.width, extent.height), (1920, 1080));

pub const fn is_zero(self) -> bool

Returns true when either axis is zero and no renderable area exists.

Examples

use ailloli_ui_render_wgpu::PhysicalExtent;
assert!(PhysicalExtent::new(0, 10).is_zero());
assert!(!PhysicalExtent::new(1, 1).is_zero());

Trait Implementations

impl Clone for PhysicalExtent

fn clone(&self) -> PhysicalExtent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PhysicalExtent

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

Formats the value using the given formatter.

impl Default for PhysicalExtent

fn default() -> PhysicalExtent

Returns the “default value” for a type.

impl Hash for PhysicalExtent

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PhysicalExtent

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