Struct KnownFontFaceRules 

struct KnownFontFaceRules {
    generation: bool,
    contents: HashMap<Atom, Vec<KnownFontFaceRule>>,
}

Fields

generation: bool

Used to distinguish new, incoming @font-face rules from existing ones.

Generations alternate between true and false, which is enough to tell one generation apart from the next.

contents: HashMap<Atom, Vec<KnownFontFaceRule>>

Maps from a font family name to a list of @font-face rules declaring fonts that belong to said family.

Implementations

impl KnownFontFaceRules

fn diff_old_and_new_font_face_rules( &mut self, stylist: &Stylist, guards: &StylesheetGuards<'_>, ) -> WebFontSetDifference

Computes the difference between the @font-face rules that are currently in effect and the ones that the Stylist knows about. The caller is notified about new or removed rules with callbacks.

Trait Implementations

impl Default for KnownFontFaceRules

fn default() -> KnownFontFaceRules

Returns the “default value” for a type.

impl MallocSizeOf for KnownFontFaceRules

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
