pub(crate) fn stats(&self) -> GlyphCacheStats

Get detailed statistics about cached glyphs.

pub(crate) fn log_atlas_stats(&self)

Log detailed atlas statistics at info level.

pub(crate) fn all_keys(&self) -> impl Iterator<Item = &GlyphCacheKey>

Returns all cached glyph keys (for debugging).

pub(crate) fn log_keys_grouped(&self)

Log all cached keys grouped by glyph ID at info level.
