The label property of the GPUExternalTexture interface provides a label that can be used to identify the object, for example in GPUError messages or console warnings.

This can be set by providing a label property in the descriptor object passed into the originating GPUDevice.importExternalTexture() call, or you can get and set it directly on the GPUExternalTexture object.

A string. If this has not been previously set as described above, it will be an empty string.

Setting and getting a label via GPUExternalTexture.label:

// ...

const externalTexture = device.importExternalTexture({
  source: video,
});

externalTexture.label = "myExtTexture";

console.log(externalTexture.label); // "myExtTexture"

Setting a label via the originating GPUDevice.importExternalTexture() call, and then getting it via GPUExternalTexture.label:

// ...

const externalTexture = device.importExternalTexture({
  source: video,
  label: "myExtTexture",
});

console.log(externalTexture.label); //  "myExtTexture"
