Struct GlyphCacheKey 

pub struct GlyphCacheKey {
    pub font_id: u64,
    pub glyph_id: u32,
    pub size: u32,
    pub variations_hash: u64,
}

Cache key for rendered glyphs

Uniquely identifies a rendered glyph by its font, glyph ID, size, and variations.

Fields

font_id: u64

Hash of font data (identifies the font)

glyph_id: u32

Glyph ID within the font

size: u32

Size in fixed-point (size * 100 for hash stability)

variations_hash: u64

Hash of variation coordinates

Implementations

impl GlyphCacheKey

pub fn new( font_data: &[u8], glyph_id: u32, size: f32, variations: &[(String, f32)], ) -> Self

Create a new cache key

Trait Implementations

impl Clone for GlyphCacheKey

fn clone(&self) -> GlyphCacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlyphCacheKey

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

Formats the value using the given formatter.

impl Hash for GlyphCacheKey

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 GlyphCacheKey

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