GPUPipelineError
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The GPUPipelineError
interface of the WebGPU API describes a pipeline failure. This is the value received when a Promise
returned by a GPUDevice.createComputePipelineAsync()
or GPUDevice.createRenderPipelineAsync()
call rejects.
Constructor
GPUPipelineError()
Experimental-
Creates a new
GPUPipelineError
object instance.
Instance properties
Inherits properties from its parent, DOMException
.
reason
Experimental Read only-
An enumerated value that defines the reason the pipeline creation failed in a machine-readable way.
Examples
In the following snippet we are attempting to create a GPUComputePipeline
using GPUDevice.createComputePipelineAsync()
. However, we have misspelt our compute pipeline entryPoint
as "maijn"
(it should be "main"
), therefore pipeline creation fails, and our catch
block prints the resulting reason and error message to the console.
js
// ...
let computePipeline;
try {
computePipeline = await device.createComputePipelineAsync({
layout: device.createPipelineLayout({
bindGroupLayouts: [bindGroupLayout],
}),
compute: {
module: shaderModule,
entryPoint: "maijn",
},
});
} catch (error) {
// error is a GPUPipelineError object instance
console.error(error.reason);
console.error(`Pipeline creation failed: ${error.message}`);
}
// ...
In this case, the given reason
is "Validation"
, and the message
is "Entry point "maijn" doesn't exist in the shader module [ShaderModule]."
