Struct bevy::render::render_graph::EmptyNode

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.

Trait Implementations§

§

impl Default for EmptyNode

§

fn default() -> EmptyNode

Returns the “default value” for a type. Read more
§

impl Node for EmptyNode

§

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

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.
§

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.
§

fn update(&mut self, _world: &mut World)

Updates internal node state using the current render World prior to the run method.

where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
