Message sent by the RenderApi to the render backend thread.

Variants

UpdateResources(Vec<ResourceUpdate>)

Add/remove/update images and fonts.

GetGlyphDimensions(FontInstanceKey, Vec<GlyphIndex>, Sender<Vec<Option<GlyphDimensions>>>)

Gets the glyph dimensions

GetGlyphIndices(FontKey, String, Sender<Vec<Option<u32>>>)

Gets the glyph indices from a string

CloneApi(Sender<IdNamespace>)

Adds a new document namespace.

CloneApiByClient(IdNamespace)

Adds a new document namespace.

AddDocument(DocumentId, DeviceIntSize, DocumentLayer)

Adds a new document with given initial size.

UpdateDocuments(Vec<DocumentId>, Vec<TransactionMsg>)

A message targeted at a particular document.

DeleteDocument(DocumentId)

Deletes an existing document.

ExternalEvent(ExternalEvent)

An opaque handle that must be passed to the render notifier. It is used by Gecko to forward gecko-specific messages to the render thread preserving the ordering within the other messages.

ClearNamespace(IdNamespace)

Removes all resources associated with a namespace.

MemoryPressure

Flush from the caches anything that isn't necessary, to free some memory.

ReportMemory(Sender<Box<MemoryReport>>)

Collects a memory report.

DebugCommand(DebugCommand)

Change debugging options.

WakeUp

Wakes the render backend's event loop up. Needed when an event is communicated through another channel.

WakeSceneBuilder

See RenderApi::wake_scene_builder.

FlushSceneBuilder(Sender<()>)

Block until a round-trip to the scene builder thread has completed. This ensures that any transactions (including ones deferred to the scene builder thread) have been processed.

ShutDown(Option<Sender<()>>)

Shut the WebRender instance down.
