Struct webrender::command_buffer::CommandBufferBuilder

pub struct CommandBufferBuilder {

Fields

kind: CommandBufferBuilderKind

establishes_sub_graph: bool

If a command buffer establishes a sub-graph, then at the end of constructing the surface, the parent surface is supplied as an input dependency, and the parent surface gets a duplicated (existing) task with the same location, and with the sub-graph output as an input dependency.

resolve_source: Option<RenderTaskId>

If this surface builds a sub-graph, it will mark a task in the filter sub-graph as a resolve source for the input from the parent surface.

extra_dependencies: Vec<RenderTaskId>

List of render tasks that depend on the task that will be created for this builder.
