Fields§
§reflector: Reflector§status: Cell<FontFaceLoadStatus>§family_name: DomRefCell<DOMString>§descriptors: DomRefCell<FontFaceDescriptors>§font_face_set: MutNullableDom<FontFaceSet>A reference to the FontFaceSet that this FontFace is a member of, if it has been
added to one. None otherwise. The spec suggests that a FontFace can be a member of
multiple FontFaceSets, but this doesn’t seem to be the case in practice, as the
FontFaceSet constructor is not exposed on the global scope.
template: RefCell<Option<(LowercaseFontFamilyName, FontTemplate)>>This holds the FontTemplate resulting from loading this FontFace, to be used when the
FontFace is added to the global FontFaceSet and thus the [FontContext].

fn validate_and_set_descriptors( &self, new_descriptors: FontFaceDescriptors, ) -> ErrorResult
Implements the body of the setter for the descriptor attributes of the FontFace interface.
https://drafts.csswg.org/css-font-loading/#fontface-interface: On setting, parse the string according to the grammar for the corresponding @font-face descriptor. If it does not match the grammar, throw a SyntaxError; otherwise, set the attribute to the serialization of the parsed value.

fn Load(&self) -> Rc<Promise>
The load() method of FontFace forces a url-based font face to request its font data and load. For fonts constructed from a buffer source, or fonts that are already loading or loaded, it does nothing. https://drafts.csswg.org/css-font-loading/#font-face-load
