Required Methods

fn new(compositor_api: CrossProcessCompositorApi, rippy_data: Vec<u8>) -> Self

where Self: Sized,

fn get_image( &self, url: ServoUrl, origin: ImmutableOrigin, cors_setting: Option<CorsSettings>, ) -> Option<Arc<Image>>

Definitively check whether there is a cached, fully loaded image available.

fn get_cached_image_status( &self, url: ServoUrl, origin: ImmutableOrigin, cors_setting: Option<CorsSettings>, use_placeholder: UsePlaceholder, ) -> ImageCacheResult

fn add_listener(&self, listener: ImageResponder)

Add a new listener for the given pending image id. If the image is already present, the responder will still receive the expected response.

fn notify_pending_response(&self, id: PendingImageId, action: FetchResponseMsg)

Inform the image cache about a response for a pending request.
