ExtractJobEntryPoints provides a generic set of callbacks for a RenderFeature compatible with the ExtractJob struct. This simplifies the work of implementing the RenderFeatureExtractJob trait.

Required Associated Types

type RenderObjectInstanceJobContextT

JobContext for the extract_render_object_instance entry point.

type RenderObjectInstancePerViewJobContextT

JobContext for the extract_render_object_instance_per_view entry point.

type FramePacketDataT: 'static + Sync + Send + FramePacketData

See definition of FramePacketData.

Required Methods

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

fn feature_index(&self) -> RenderFeatureIndex

Provided Methods

fn begin_per_frame_extract( &self, _context: &ExtractPerFrameContext<'extract, '_, Self>, )

Called once at the start of the extract step when any RenderView in the frame is relevant to this RenderFeature.

fn extract_render_object_instance( &self, _job_context: &mut Self::RenderObjectInstanceJobContextT, _context: &ExtractRenderObjectInstanceContext<'extract, '_, Self>, )

Called once for each instance of an Entity and RenderObject in the frame matching this RenderFeature.

fn extract_render_object_instance_per_view( &self, _job_context: &mut Self::RenderObjectInstancePerViewJobContextT, _context: &ExtractRenderObjectInstancePerViewContext<'extract, '_, Self>, )

Called once for each instance of an Entity and RenderObject in each RenderView relevant to this RenderFeature.

fn end_per_view_extract( &self, _context: &ExtractPerViewContext<'extract, '_, Self>, )

Called once for each relevant RenderView. This function is only run after all instances of extract_render_object_instance_per_view have finished for that RenderView.

fn end_per_frame_extract( &self, _context: &ExtractPerFrameContext<'extract, '_, Self>, )

Called once at the end of the extract step when any RenderView in the frame is relevant to this RenderFeature.

fn new_render_object_instance_job_context( &'extract self, ) -> Option<Self::RenderObjectInstanceJobContextT>

fn new_render_object_instance_per_view_job_context( &'extract self, ) -> Option<Self::RenderObjectInstancePerViewJobContextT>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
