Expand description

Represents a transaction in the format sent through the channel.

Fields§

§document_id: DocumentId

§scene_ops: Vec<SceneMsg>

Changes that require re-building the scene.

§frame_ops: Vec<FrameMsg>

Changes to animated properties that do not require re-building the scene.

§resource_updates: Vec<ResourceUpdate>

Updates to resources that persist across display lists.

§generate_frame: GenerateFrame

Whether to trigger frame building and rendering if something has changed.

§creation_time: Option<u64>

Creation time of this transaction.

§invalidate_rendered_frame: bool

Whether to force frame building and rendering even if no changes are internally observed.

§use_scene_builder_thread: bool

Whether to enforce that this transaction go through the scene builder.

§low_priority: bool

§notifications: Vec<NotificationRequest>

Handlers to notify at certain points of the pipeline.

§blob_rasterizer: Option<Box<dyn AsyncBlobImageRasterizer>>

§blob_requests: Vec<BlobImageParams>

§rasterized_blobs: Vec<(BlobImageRequest, BlobImageResult)>

§profile: TransactionProfile

Collect various data along the rendering pipeline to display it in the embedded profiler.

§render_reasons: RenderReasons

Keep track of who asks rendering to happen.
