Struct GlyphKey

pub struct GlyphKey {
    pub face_id: u64,
    pub font_index: u32,
    pub px_size: u16,
    pub glyph_id: u32,
    pub scale_100: u16,
}

Cache key for one rasterized glyph in the text atlas.

Examples

use ailloli_ui_render_wgpu::text::GlyphKey;
let key = GlyphKey { face_id: 3, font_index: 0, px_size: 16,
    glyph_id: 42, scale_100: 200 };
assert_eq!((key.face_id, key.scale_100), (3, 200));

Fields

face_id: u64

Stable face identity supplied by the text system.

font_index: u32

Face index inside a font collection.

px_size: u16

Raster size in physical pixels, clamped to 8..=128 when used.

glyph_id: u32

Font-specific glyph identifier; rasterization narrows it to u16.

scale_100: u16

round(dpr * 100) to separate HiDPI cache buckets.

Trait Implementations

impl Clone for GlyphKey

fn clone(&self) -> GlyphKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GlyphKey

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

Formats the value using the given formatter.

impl Hash for GlyphKey

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 GlyphKey

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