`throwOnExhausted: false` returns a `RetryRunResult` instead of throwing.

```ts
const result = await runRetryPolicy(
  policy,
  async () => {
    return await doWork();
  },
  { throwOnExhausted: false },
);

if (result.ok) {
  console.log(result.value);
} else {
  console.error("Failed after", result.attempts, "attempts:", result.error);
}
```

On failure, `result.error` is a `RetryError` (retries exhausted, or a caught value the policy's `isKnownError` rejected as outside its error domain) or an `AbortError` (run canceled).

:::note

In result mode, `runRetryPolicy(...)` never throws for a failed `execute(...)` attempt — an `isKnownError`-rejected value is wrapped in a `RetryError` and returned on `result.error`, not thrown. See [Narrow the Error Domain](/retry/custom-policies#narrow-the-error-domain).

:::

Aborting a run behaves the same way in this mode — see [Cancellation](/retry/abort-signal#non-throw-mode).
