Struct RunGraphOnViewNode

pub struct RunGraphOnViewNode { /* private fields */ }

A RenderGraph Node that runs the configured subgraph once. This makes it easier to insert sub-graph runs into a graph.

Implementations

impl RunGraphOnViewNode

pub fn new<T: RenderSubGraph>(sub_graph: T) -> Self

Trait Implementations

impl Node for RunGraphOnViewNode

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.
