Module render_graph 

Render Graph — declarative, dependency-ordered GPU pass scheduling.

The render graph describes the full frame as a directed acyclic graph (DAG) of render passes, each consuming and producing named resources (textures, render targets, buffers). The graph compiler topologically sorts passes, deduces resource lifetimes, inserts memory barriers, and drives execution.

Key Types

• RenderGraph — builder: declare passes and resources
• CompiledGraph — sorted, barrier-annotated execution plan
• PassBuilder — fluent API for declaring a single pass
• ResourceDesc — describes a texture or buffer resource
• RenderPass — one node in the graph
• PassKind — Graphics, Compute, or Transfer
• ResourceAccess — read / write access mode
• Barrier — memory / layout transition between passes

Structs

Barrier

A memory / image-layout barrier between two passes.

CompileStats

CompiledGraph

The output of graph compilation: passes in execution order with barriers.

CompiledPass

A pass in the compiled execution order, with pre-computed barriers.

PassBuilder

Fluent builder for a single render pass.

RenderGraph

Builder for a frame’s render graph.

RenderPass

A single node in the render graph.

ResourceDesc

Description of a render graph texture resource.

Enums

GraphError

PassKind

What kind of work a render pass performs.

ResourceAccess

How a pass accesses a resource.

ResourceSize

Size of a render graph resource, possibly relative to the output framebuffer.

TextureFormat

Format of a texture resource.
