Struct GraphInputNode

pub struct GraphInputNode { /* private fields */ }

A Node which acts as an entry point for a RenderGraph with custom inputs. It has the same input and output slots and simply copies them over when run.

Trait Implementations

impl Node for GraphInputNode

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

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