Konstruktion speichersicherer Binärpuffer in Svelte Writable Stores mittels SharedArrayBuffer-Wrappern

import { writable } from 'svelte/store';
 
export function createSharedBufferStore(byteLength) {
  const sab = new SharedArrayBuffer(byteLength);
  const view = new Int32Array(sab);
  const { subscribe, set } = writable(view);
 
  return {
    subscribe,
    updateAt(index, value) {
      Atomics.store(view, index, value);
      set(new Int32Array(sab));
    },
    getValueAt(index) {
      return Atomics.load(view, index);
    }
  };
}
