GPURenderBundleEncoder: pushDebugGroup() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

See full compatibility

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Note: This feature is available in Web Workers.

The pushDebugGroup() method of the GPURenderBundleEncoder interface begins a render bundle debug group, which is marked with a specified label, and will contain all subsequent encoded commands up until a popDebugGroup() method is invoked.

This could be used for telemetry, or may be utilized in GPUError messages, browser dev tools, or other services in the future to help with debugging.

Note: This method is functionally identical to its equivalent on GPURenderPassEncoder — pushDebugGroup().

Syntax

pushDebugGroup(groupLabel)

Parameters

groupLabel: A string representing the label for the debug group.

Return value

None (Undefined).

Examples

// …

const bundleEncoder = device.createRenderBundleEncoder(renderBundleDescriptor);

bundleEncoder.pushDebugGroup("my_group_marker"); // Start labeled debug group

bundleEncoder.setPipeline(renderPipeline);
bundleEncoder.setVertexBuffer(0, vertexBuffer);
bundleEncoder.draw(3);

bundleEncoder.popDebugGroup();

// …
