GPU: wgslLanguageFeatures 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 wgslLanguageFeatures read-only property of the GPU interface returns a WGSLLanguageFeatures object that reports the WGSL language extensions supported by the WebGPU implementation.

Note: Not all WGSL language extensions are available to WebGPU in all browsers that support the API. We recommend you thoroughly test any extensions you choose to use.

Value

A WGSLLanguageFeatures object instance. This is a setlike object.

Examples

js
if (!navigator.gpu) {
  throw Error("WebGPU not supported.");
}

const wgslFeatures = navigator.gpu.wgslLanguageFeatures;

// Return the size of the set
console.log(wgslFeatures.size);

// Iterate through all the set values using values()
const valueIterator = wgslFeatures.values();
for (const value of valueIterator) {
  console.log(value);
}

// …
