WasmGPU.interop.viewFromHandle¶
Summary¶
WasmGPU.interop.viewFromHandle reconstructs a typed view from a serialized WasmSliceHandle.
This is useful when passing handles across API boundaries and restoring typed access later.
Syntax¶
WasmGPU.interop.viewFromHandle(buffer: ArrayBufferLike, handle: WasmSliceHandle): ArrayBufferView
const view = wgpu.interop.viewFromHandle(buffer, handle);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
buffer |
ArrayBufferLike |
Yes | Buffer that owns the pointer region described by handle. |
handle |
WasmSliceHandle |
Yes | Handle containing kind/dtype/pointer/length metadata. |
Returns¶
ArrayBufferView - Typed array instance selected from handle.dtype.
Type Details¶
type WasmSliceHandle = {
kind: "heap" | "frame" | "arena";
dtype: "f32" | "u32" | "i32" | "u8";
ptr: number;
length: number;
epoch?: number;
};
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const slice = wgpu.interop.heap.allocU32(4);
slice.write([11, 22, 33, 44]);
const handle = slice.handle();
const restored = wgpu.interop.viewFromHandle(wgpu.interop.buffer(), handle);
console.log(restored);
slice.free();
