GPUCompilationMessage: offset property

Limited availability

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

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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 offset read-only property of the GPUCompilationMessage interface is a number representing the offset from the start of the shader code to the exact point, or the start of the relevant substring, that the message corresponds to.

Value

A number.

To be precise, offset is the number of UTF-16 code units from the beginning of the shader code to the exact point or start of the relevant substring that the message corresponds to.

If the message does not correspond to a specific code position (perhaps it refers to the whole of the shader code), offset will be 0.

Examples

js
  // ...
  const shaderModule = device.createShaderModule({
    code: shaders,
  });

  const shaderInfo = await shaderModule.getCompilationInfo();
  const firstMessage = shaderInfo.messages[0];
  console.log(firstMessage.offset);
  // ...
}

See the main GPUCompilationInfo page for a more detailed example.
