GPUCompilationMessage: length property

Limited availability

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

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 length read-only property of the GPUCompilationMessage interface is a number representing the length of the substring that the message corresponds to.

Value

A number.

To be precise, length is the number of UTF-16 code units in the shader code substring that the message corresponds to. If the message corresponds to a single point rather than a substring, length will be 0.

Examples

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

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

See the main GPUCompilationInfo page for a more detailed example.
