GPURenderPipeline: label 屬性
注意：此功能在 Web Workers 中可用。
GPURenderPipeline 介面的 label 屬性提供了一個可用於標識物件的標籤，例如在 GPUError 訊息或控制檯警告中。
可以透過在傳遞給 GPUDevice.createRenderPipeline() 或 GPUDevice.createRenderPipelineAsync() 呼叫的描述符物件中提供 label 屬性來設定它，或者您可以直接在 GPURenderPipeline 物件上獲取和設定它。
值
一個字串。如果之前未按上述方式設定，則為空字串。
示例
透過 GPURenderPipeline.label 設定和獲取標籤
js
// …
const pipelineDescriptor = {
vertex: {
module: shaderModule,
entryPoint: "vertex_main",
buffers: vertexBuffers,
},
fragment: {
module: shaderModule,
entryPoint: "fragment_main",
targets: [
{
format: navigator.gpu.getPreferredCanvasFormat(),
},
],
},
primitive: {
topology: "triangle-list",
},
layout: "auto",
};
const renderPipeline = device.createRenderPipeline(pipelineDescriptor);
renderPipeline.label = "my_render_pipeline";
console.log(renderPipeline.label); // "my_render_pipeline"
透過 GPUDevice.createRenderPipeline() 呼叫設定標籤，然後透過 GPURenderPipeline.label 獲取它
js
// …
const pipelineDescriptor = {
vertex: {
module: shaderModule,
entryPoint: "vertex_main",
buffers: vertexBuffers,
},
fragment: {
module: shaderModule,
entryPoint: "fragment_main",
targets: [
{
format: navigator.gpu.getPreferredCanvasFormat(),
},
],
},
primitive: {
topology: "triangle-list",
},
layout: "auto",
label: "my_render_pipeline",
};
const renderPipeline = device.createRenderPipeline(pipelineDescriptor);
console.log(renderPipeline.label); // "my_render_pipeline"
