Enum OwnedFontSource 

pub enum OwnedFontSource {
    Memory(FcFont),
    Disk(FcFontPath),
}

Owned font-source descriptor, returned by FcFontCache::get_font_by_id.

In v4.0 this was a borrowed enum (FontSource<'a> with refs into the pattern map). With v4.1’s shared-state cache, the map lives behind an RwLock, so returning a reference would require the caller to hold a read guard for the full lifetime of the result — which bleeds the locking strategy into every call site. The owned variant clones the small FcFont / FcFontPath struct and releases the lock immediately. Bytes/mmap are not cloned — those go through get_font_bytes which hands out Arc<FontBytes>.

Variants

Memory(FcFont)

Font loaded from memory (small metadata + owned Vec<u8>).

Disk(FcFontPath)

Font loaded from disk.
