Struct bevy_render::render_graph::RenderGraphContext
source · [−]pub struct RenderGraphContext<'a> { /* private fields */ }
Expand description
The context with all graph information required to run a Node
.
This context is created for each node by the RenderGraphRunner
.
The slot input can be read from here and the outputs must be written back to the context for passing them onto the next node.
Sub graphs can be queued for running by adding a RunSubGraph
command to the context.
After the node has finished running the graph runner is responsible for executing the sub graphs.
