pub struct EmptyNode;Expand description
A Node without any inputs, outputs and subgraphs, which does nothing when run.
Used (as a label) to bundle multiple dependencies into one inside
the RenderGraph.

source§fn run(
&self,
_graph: &mut RenderGraphContext<'_>,
_render_context: &mut RenderContext<'_>,

_world: &World
) -> Result<(), NodeRunError>
fn run( &self, _graph: &mut RenderGraphContext<'_>, _render_context: &mut RenderContext<'_>, _state: &RenderResources, _world: &World ) -> Result<(), NodeRunError>
Runs the graph node logic, issues draw calls, updates the output slots and
optionally queues up subgraphs for execution. The graph data, input and output values are
passed via the
RenderGraphContext.source§fn input(&self) -> Vec<SlotInfo>
fn input(&self) -> Vec<SlotInfo>
Specifies the required input slots for this node.
They will then be available during the run method inside the
RenderGraphContext.source§fn output(&self) -> Vec<SlotInfo>
fn output(&self) -> Vec<SlotInfo>
Specifies the produced output slots for this node.
They can then be passed one inside
RenderGraphContext during the run method.source§fn update(&mut self, _state: &mut RenderResources)
fn update(&mut self, _state: &mut RenderResources)
Updates internal node state using the current
RenderResources prior to the run method.Auto Trait Implementations§
