Function forEachPage

forEachPage<Page>(
fetcher: PageFetcher<Page>,
callback: (page: NonNullable<Page>, index: number) => void,
): Promise<void>
Fetches multiple pages in parallel and invokes a callback for each non-nullish page.
Type Parameters
- Page
  The page data type.
Parameters
- fetcher: PageFetcher<Page>
  Fetches a page by zero-based index.
- callback: (page: NonNullable<Page>, index: number) => void
  Called for each non-nullish page (may be out-of-order).
Returns Promise<void>
Resolves when all pages are fetched.
Remarks
All pages are fetched in parallel with no concurrency limit; consider using rateLimited to wrap the fetcher. If a page reports a higher num_pages, additional pages are fetched automatically.

Throws
Rejects immediately if any fetch fails; in-flight fetches continue but are ignored.
Example
```
await forEachPage(
  async (i) => ({ num_pages: 5, page: await fetchUsers(i) }),
  (users, i) => console.log(`Page ${i}:`, users),
);
```
