Read a property value.

fn write_property( &mut self, property: PropertyIdentifier, _array_index: Option<u32>, value: PropertyValue, _priority: Option<u8>, ) -> Result<(), Error>

Write a property value.

fn property_list(&self) -> Cow<'static, [PropertyIdentifier]>

List all properties this object supports.

fn required_properties(&self) -> Cow<'static, [PropertyIdentifier]>
