LocalCache type

A cache owned by one controller — no sharing across the tree. Returned bycreateCache(ctx, fetcher, options?). Disposed automatically with the controller.

Signature:

type LocalCache<T> = AsyncState<T> & {
  invalidate(): Promise<void>;
  setData(updater: (prev: T | undefined) => T): Snapshot;
  write(updater: (prev: T | undefined) => T): void;
  replace(value: T): void;
  dispose(): void;
};
