pub(crate) enum UnscaledStyleMetricsSet {
    Precomputed(Vec<UnscaledStyleMetrics>),
    Lazy(Arc<RwLock<Vec<Option<UnscaledStyleMetrics>>>>),
}

Implementations

impl UnscaledStyleMetricsSet

pub fn precomputed( font: &FontRef<'_>, coords: &[F2Dot14], shaper_mode: ShaperMode, style_map: &GlyphStyleMap, ) -> Self

Creates a precomputed style metrics set containing all metrics required by the glyph map.

pub fn lazy(style_map: &GlyphStyleMap) -> Self
