Implementations

impl ImageCacheImpl

Require self.store.lock() before calling.

Trait Implementations

impl ImageCache for ImageCacheImpl

fn add_listener(&self, listener: ImageLoadListener)

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.

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

fn memory_report(&self, prefix: &str, ops: &mut MallocSizeOfOps) -> Report

fn get_image( &self, url: ServoUrl, origin: ImmutableOrigin, cors_setting: Option<CorsSettings>, ) -> Option<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_rasterization_complete_listener( &self, pipeline_id: PipelineId, image_id: PendingImageId, requested_size: DeviceIntSize, sender: IpcSender<ImageCacheResponseMessage>, )

Adds a new listener to be notified once the given image_id has been rasterized at the given size. The listener will receive a VectorImageRasterizationComplete message on the given sender, even if the listener is called after rasterization at has already completed.

fn rasterize_vector_image( &self, image_id: PendingImageId, requested_size: DeviceIntSize, ) -> Option<RasterImage>

Returns Some if the given image_id has already been rasterized at the given size. Otherwise, triggers a new job to perform the rasterization. If a notification is needed after rasterization is completed, the add_rasterization_complete_listener API below can be used to add a listener.

fn create_new_image_cache( &self, pipeline_id: Option<PipelineId>, compositor_api: CrossProcessCompositorApi, ) -> Arc<dyn ImageCache>

Create new image cache based on this one, while reusing the existing thread_pool.

fn fill_key_cache_with_batch_of_keys(&self, image_keys: Vec<WebRenderImageKey>)

Fills the image cache with a batch of keys.
