Struct GlyphCellKey 

pub struct GlyphCellKey {
    pub font_hash: u64,
    pub glyph_id: u16,
    pub ppem: u16,
    pub scale_fixed: u32,
    pub subpx_x: u8,
    pub subpx_y: u8,
}

Cache key for pre-rasterized glyph cells. Includes sub-pixel x/y fractional position quantized to 1/4 pixel.

Fields

font_hash: u64

glyph_id: u16

ppem: u16

scale_fixed: u32

Scale factor encoded as fixed-point (scale * 65536) for unhinted glyphs. 0 for hinted glyphs (already in pixel coords).

subpx_x: u8

Sub-pixel x position quantized to 1/4 pixel (0..3).

subpx_y: u8

Sub-pixel y position quantized to 1/4 pixel (0..3).

Trait Implementations

impl Clone for GlyphCellKey

fn clone(&self) -> GlyphCellKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GlyphCellKey

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

Formats the value using the given formatter.

impl Hash for GlyphCellKey

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 GlyphCellKey

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