Struct IconKey

pub struct IconKey {
    pub icon: IconId,
    pub px_size: u16,
    pub scale_100: u16,
}

Cache key for a rasterized icon at a given size and DPR bucket.

px_size is the physical square side and scale_100 is the rounded device pixel ratio multiplied by 100. Both participate in equality and hashing.

Examples

use ailloli_ui_core::IconId;
use ailloli_ui_render_wgpu::IconKey;
let key = IconKey { icon: IconId::Plus, px_size: 24, scale_100: 150 };
assert_eq!((key.px_size, key.scale_100), (24, 150));

Fields

icon: IconId

Logical icon source identity.

px_size: u16

Raster texture side length in physical pixels.

scale_100: u16

Device-pixel-ratio bucket, round(dpr * 100), clamped to 1..=u16::MAX.

Trait Implementations

impl Clone for IconKey

fn clone(&self) -> IconKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IconKey

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

Formats the value using the given formatter.

impl Hash for IconKey

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 IconKey

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