Struct FontEntry 

pub struct FontEntry {
    pub fontdb_id: ID,
    pub face_index: u32,
    pub swash_cache_key: CacheKey,
    pub is_system: bool,
    /* private fields */
}

Fields

fontdb_id: ID

face_index: u32

swash_cache_key: CacheKey

is_system: bool

True for faces discovered via the OS font enumeration. Glyph fallback prefers explicitly-registered faces and only reaches for system faces as a last resort (see find_fallback_font).

Implementations

impl FontEntry

pub fn bytes(&self) -> &[u8]

Borrow the underlying font bytes, loading them from disk on first use for lazily-tracked system faces. Returns an empty slice if a system font file can no longer be read (uninstalled mid-session); shaping then degrades gracefully to None/.notdef.

pub fn shaper_data(&self, font: &FontRef<'_>) -> &ShaperData

Borrow this face’s shaping tables, building them on first use.

ShaperData::new reprocesses the font tables; doing it once per face (instead of once per shape call) avoids redundant work on every relayout/keystroke. The font must refer to this same face — callers already hold a FontRef opened from bytes().
