    ) -> RafxResult<()> { ... }
}

A type-erased trait used by the Renderer, RenderFrameJob, and RendererThreadPool to control the workload of the rendering process without identifying specific types used in each RenderFeature’s frame packet or workload.

Required Methods

fn render_submit_node( &self, _write_context: &mut RenderJobCommandBufferContext<'_, '_>, args: RenderSubmitNodeArgs, ) -> RafxResult<()>

Called by PreparedRenderData in write_view_phase for each RenderFeatureSubmitNode associated with this RenderFeature. This is normally where the actual GPU draw commands are implemented for the RenderFeature. Each series of calls to render_submit_node will be preceded by a single call to begin_submit_node_batch.

fn feature_debug_constants(&self) -> &'static RenderFeatureDebugConstants

fn feature_index(&self) -> RenderFeatureIndex

Provided Methods

fn on_begin_execute_graph( &self, _begin_execute_graph_context: &mut RenderJobBeginExecuteGraphContext, ) -> RafxResult<()>

Called once at the start of executing the PreparedRenderData in PreparedRenderGraph::execute_graph. This can be used to start GPU transfers or other work prior to drawing any submit nodes related to this RenderFeature.

fn begin_submit_node_batch( &self, _write_context: &mut RenderJobCommandBufferContext<'_, '_>, _args: BeginSubmitNodeBatchArgs, ) -> RafxResult<()>

Called by PreparedRenderData in write_view_phase whenever the current RenderFeatureIndex changes into this RenderFeature OR when the sort_key changes. This can be used to setup pipelines or other expensive state changes that can remain constant for subsequent render_submit_node calls.
