Explainer No information provided Specification https://github.com/gpuweb/gpuweb/pull/5389 Summary Add a language feature to WGSL, `texture_and_sampler_let` that adds the ability to store texture and sampler objects into a let declaration in WGSL. Blink component Blink>WebGPU Web Feature ID webgpu Motivation To allow storing texture and samples in WGSL shaders into lets. This allows creating local names for what are usually global objects. Initial public proposal https://github.com/gpuweb/gpuweb/issues/5339 TAG review No information provided TAG review status Pending Risks Interoperability and Compatibility This feature has been approved in W3C GPU for the Web WG meetings including participants from Safari and Firefox. Meeting minutes: https://docs.google.com/document/d/1kTmVO9okQZOotWtCNDzRaF-rPXgyIVJ-u5PEe7rnjQc/edit?tab=t.0#bookmark=id.u8bh2sfreh45 Gecko: No signal Mozilla members have approved https://github.com/gpuweb/gpuweb/pull/5389 and requested during weekly standardization meetings that we postpone filing standard positions until we reach Candidate Recommendation (CR) status in Q4. WebKit: Closed Without a Position (https://github.com/WebKit/standards-positions/issues/294#issuecomment-1877411933) Web developers: No signals Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? No information provided Debuggability No information provided Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? No All platforms will eventually have support. Will immediately be available on Android, Android WebView, ChromeOS, Mac, and Windows, where hardware support is available. Linux is planned to have WebGPU support in the future, so this feature will become available when WebGPU does. Is this feature fully tested by web-platform-tests? Yes WebGPU/WGSL have a conformance test suite (https://github.com/gpuweb/cts) that is regularly pulled into Chromium and part of the testing of Dawn/Tint in Chromium. While the CTS can be embedded in WPT, the WebGPU team opted to keep it separate in Chromium testing to use a customized harness for robustness and performance.

Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way).
