Struct GlyphKey 

struct GlyphKey {
    font: u32,
    size_q: u16,
    glyph_id: u16,
}

Cache key for one rasterised glyph.

Fields

font: u32

size_q: u16

ab_glyph uses f32 for px size but maps it to an integer PxScale internally; we quantise so the cache hit-rate stays high. Half-pixel steps give plenty of fidelity at the sizes MD2 uses (16..80).

glyph_id: u16

Trait Implementations

impl Clone for GlyphKey

fn clone(&self) -> GlyphKey

Returns a duplicate 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.
