Struct GlyphCacheKey 

pub struct GlyphCacheKey {
    pub font_face_id: FontFaceId,
    pub glyph_id: u16,
    pub size_bits: u32,
    pub weight: u32,
    pub hinted: bool,
}

Fields

font_face_id: FontFaceId

glyph_id: u16

size_bits: u32

weight: u32

Font weight (variation axis) so that e.g. Inter Regular and Inter Bold produce separate cache entries even though they share the same font_face_id and glyph_id in a variable font.

hinted: bool

Whether the bitmap was rasterized with hinting. Rasters produced under a raster scale (zoomed content) are unhinted, and the same physical size can be reached both ways — 7px at raster_scale 2 and 14px at raster_scale 1 share size_bits but must not share a bitmap.

Implementations

impl GlyphCacheKey

pub fn new(font_face_id: FontFaceId, glyph_id: u16, size_px: f32) -> Self

pub fn with_weight( font_face_id: FontFaceId, glyph_id: u16, size_px: f32, weight: u32, hinted: bool, ) -> Self

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 Copy for GlyphCacheKey

impl Debug for GlyphCacheKey

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

Formats the value using the given formatter.

impl Eq for GlyphCacheKey

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.
