+    WebGPU is an API that exposes the capabilities of GPU hardware for the Web. The API is designed from the ground up to efficiently map to (post-2014) native GPU APIs. WebGPU is not related to WebGL and does not explicitly target OpenGL ES.
+	wgpu-native is a native WebGPU implementation in Rust, based on wgpu-core, with C bindings.
