WasmGPU.interop.heap.allocI32¶
Summary¶
WasmGPU.interop.heap.allocI32 allocates heap-owned signed 32-bit storage as WasmSlice<Int32Array>.
This is useful for offsets, signed indices, and sentinel-based metadata.
Syntax¶
WasmGPU.interop.heap.allocI32(len: number): WasmSlice<Int32Array>
const slice = wgpu.interop.heap.allocI32(len);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
len |
number |
Yes | Number of int32 elements to allocate. |
Returns¶
WasmSlice<Int32Array> - Heap slice of int32 data.
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const signed = wgpu.interop.heap.allocI32(4);
signed.write([-1, 0, 1, 2]);
console.log(signed.view());
signed.free();
