WasmGPU.interop.heap.allocU32 allocates heap-owned unsigned 32-bit storage as a WasmSlice<Uint32Array>. Use this for index lists, counts, and integer metadata that must persist across frames.

Syntax

WasmGPU.interop.heap.allocU32(len: number): WasmSlice<Uint32Array>
const slice = wgpu.interop.heap.allocU32(len);

Parameters

Name Type Required Description
len number Yes Number of uint32 elements to allocate.

Returns

WasmSlice<Uint32Array> - Heap slice of uint32 data.

Example

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const ids = wgpu.interop.heap.allocU32(5);
ids.write([2, 4, 6, 8, 10]);
console.log(ids.view()[3]);
