Struct bevy::render::render_graph::RenderGraphContext [−]
pub struct RenderGraphContext<'a> { /* fields omitted */ }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.
Implementations
impl<'a> RenderGraphContext<'a>
impl<'a> RenderGraphContext<'a>
Creates a new render graph context for the node.
pub fn input_info(&self) -> &SlotInfos
pub fn input_info(&self) -> &SlotInfos
Returns the SlotInfos of the inputs.
pub fn output_info(&self) -> &SlotInfos
pub fn output_info(&self) -> &SlotInfos
Returns the SlotInfos of the outputs.

label: impl Into<SlotLabel>
) -> Result<&TextureView, InputSlotError>
pub fn get_input_texture(
&self,
label: impl Into<SlotLabel>
) -> Result<&TextureView, InputSlotError>

&self,
label: impl Into<SlotLabel>
) -> Result<Entity, InputSlotError>
pub fn get_input_entity(
&self,
label: impl Into<SlotLabel>
) -> Result<Entity, InputSlotError>
Retrieves the input slot value referenced by the label as an Entity.
pub fn set_output(
&mut self,
label: impl Into<SlotLabel>,
value: impl Into<SlotValue>
) -> Result<(), OutputSlotError>
pub fn set_output(
&mut self,
label: impl Into<SlotLabel>,
value: impl Into<SlotValue>
) -> Result<(), OutputSlotError>
Sets the output slot value referenced by the label.
pub fn run_sub_graph(
&mut self,
name: impl Into<Cow<'static, str>>,
inputs: Vec<SlotValue, Global>
) -> Result<(), RunSubGraphError>
pub fn run_sub_graph(
&mut self,
name: impl Into<Cow<'static, str>>,
inputs: Vec<SlotValue, Global>
) -> Result<(), RunSubGraphError>
Queues up a sub graph for execution after the node has finished running.
