The getBindGroupLayout() method of the GPURenderPipeline interface returns the pipeline's GPUBindGroupLayout object with the given index (i.e. included in the originating GPUDevice.createRenderPipeline() or GPUDevice.createRenderPipelineAsync() call's pipeline layout).
If the GPURenderPipeline was created with layout: "auto", this method is the only way to retrieve the GPUBindGroupLayouts generated by the pipeline.
getBindGroupLayout(index)
A GPUBindGroupLayout object instance.
The following criteria must be met when calling getBindGroupLayout(), otherwise a GPUValidationError is generated and an invalid GPUBindGroupLayout object is returned:
Note: You can see complete working examples with getBindGroupLayout() in action in the WebGPU samples.
