WasmGPU.interop.isSharedMemory¶

Summary¶

WasmGPU.interop.isSharedMemory reports whether WebAssembly memory is a SharedArrayBuffer. Use this check before enabling cross-thread workflows that require shared memory semantics.

Syntax¶

WasmGPU.interop.isSharedMemory(): boolean
const shared = wgpu.interop.isSharedMemory();

Parameters¶

This API does not take parameters.

Returns¶

boolean - true when memory is shared, otherwise false.

Example¶

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

if (!wgpu.interop.isSharedMemory()) {
    console.warn("Shared memory disabled; use cross-origin isolation + shared build.");
}
