compute.CPUndarray#backingBytes¶

Summary¶

compute.CPUndarray#backingBytes returns a Uint8Array view of raw backing storage. This view includes the entire allocated byte region, including non-contiguous layouts and offsets. Use it for byte-level inspection, custom serialization, or bulk zeroing/copy logic. For contiguous typed element access, prefer data(). The returned view aliases WebAssembly memory. Discard and reacquire it after that memory grows, and do not use it after the ndarray is destroyed.

Syntax¶

CPUndarray.backingBytes(): Uint8Array<ArrayBuffer>
const bytes = a.backingBytes();

Parameters¶

This API does not take parameters.

Returns¶

Uint8Array<ArrayBuffer> - Raw byte view over CPU ndarray backing memory.

Example¶

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

const a = wgpu.compute.CPUndarray.zeros("u16", { shape: [4] });
const bytes = a.backingBytes();
bytes[0] = 255;
console.log(bytes.byteLength, a.get(0));
a.destroy();
