Struct GlyphCache 

pub struct GlyphCache { /* private fields */ }

A cache for pre-built glyph paths to avoid re-parsing font data and re-building paths for each character occurrence.

Implementations

impl GlyphCache

pub fn new(capacity: usize) -> Self

pub fn with_default_capacity() -> Self

pub fn get_or_insert( &mut self, font_data: &[u8], glyph_id: u16, build_fn: impl FnOnce() -> Option<Path>, ) -> Option<&Path>

Get or insert a glyph path.

font_data is the raw font file bytes. glyph_id is the glyph index. build_fn is called on cache miss to build the path.

pub fn hit_rate(&self) -> f64

Cache hit rate for debugging/profiling.

pub fn len(&self) -> usize

Number of cached entries.

pub fn is_empty(&self) -> bool

Whether the cache is empty.

pub fn clear(&mut self)

Clear the cache and reset statistics.
