Fields

scene_size: SizeU16

Tile-aligned dimensions of the root scene.

nodes: Vec<Node>

The nodes of the root layer.

draws: Vec<D>

Flat storage for all draw commands that are part of the recording.

layers: Vec<RecordedLayer>

Data about recorded layers, indexed by their ID.

filter_layers: Vec<u32>

IDs of recorded filter layers in creation order.

root_is_blend_target: bool

Whether the root is the target of a non-default blending operation.

max_layer_depth: usize

Maximum layer depth across the whole layer graph.

largest_layer_size: Option<SizeU16>

The largest dimensions of any recorded layer.

largest_filter_layer_size: Option<SizeU16>

The largest dimensions of any recorded filter layer.

has_non_default_blend: bool

Whether there exists at least one layer that uses a non-default blend mode.
