WasmGPU.interop.heap.allocU8

Summary

WasmGPU.interop.heap.allocU8 allocates heap-owned byte storage and returns WasmSlice<Uint8Array>. Optional alignment checks can be requested for interop with alignment-sensitive native code.

Syntax

WasmGPU.interop.heap.allocU8(len: number, align?: number): WasmSlice<Uint8Array>
const slice = wgpu.interop.heap.allocU8(len, align);

Parameters

Name Type Required Description
len number Yes Number of bytes to allocate.
align number No Alignment requirement check, default 16.

Returns

WasmSlice<Uint8Array> - Heap byte slice.

Example

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

const packet = wgpu.interop.heap.allocU8(64, 16);
packet.view().set([0xde, 0xad, 0xbe, 0xef]);
console.log(packet.ptr.toString(16), packet.byteLength);
packet.free();
