# ComputeNodeGraph.PipelinesDescriptor

Specifies the configuration used to compile a set of compute pipelines for a compute graph effect.

## Declaration

```swift
struct PipelinesDescriptor
```

## Overview

Overview Use a descriptor when you need explicit control over pipeline compilation — for example, to supply Metal libraries from multiple bundles or to enable debug draw. Pass the configured descriptor to ComputeNodeGraph.Pipelines/init(descriptor:) to compile. var descriptor = ComputeNodeGraph.PipelinesDescriptor(assembly: assembly) descriptor.addLibrary(myMTLLibrary, bundle: "com.example.MyEffects") descriptor.options.debugDraw = true let pipelines = try await ComputeNodeGraph.Pipelines(descriptor: descriptor)
