Struct CacheManager 

pub struct CacheManager {
    pub shaping_cache: MultiLevelCache<ShapingCacheKey, Arc<Vec<u8>>>,
    pub glyph_cache: MultiLevelCache<GlyphCacheKey, Arc<Vec<u8>>>,
}

Centralized cache manager for shaping and glyph caches

Fields

shaping_cache: MultiLevelCache<ShapingCacheKey, Arc<Vec<u8>>>

glyph_cache: MultiLevelCache<GlyphCacheKey, Arc<Vec<u8>>>

Implementations

impl CacheManager

pub fn new() -> Self

Create a manager with sensible default sizes

Default capacities are conservative to prevent memory issues:

• Shaping: 10,100 entries (shapes are larger)
• Glyphs: 101,000 entries (individual glyphs are smaller)

pub fn get_shaped(&self, key: &ShapingCacheKey) -> Option<Arc<Vec<u8>>>

Look up previously shaped text

pub fn cache_shaped(&self, key: ShapingCacheKey, data: Arc<Vec<u8>>)

Save shaping results for next time

pub fn get_glyph(&self, key: &GlyphCacheKey) -> Option<Arc<Vec<u8>>>

Find a rendered glyph we cached earlier

pub fn cache_glyph(&self, key: GlyphCacheKey, data: Arc<Vec<u8>>)

Remember this glyph for future renders

pub fn report_metrics(&self) -> String

Human-readable performance report

pub fn clear_all(&self)

Clears all entries in both shaping and glyph caches, and resets their statistics.

Trait Implementations

impl Default for CacheManager

fn default() -> Self

Returns the “default value” for a type.
