# run()

Runs the generator and returns a stream of newly synthesized samples.

```
nonisolated func run() -> some AsyncSequence<SampleType, any Error>
```

## Return Value

An async throwing stream of individual samples.

## Discussion

Each element the stream yields is a newly generated sample. After iteration
completes, access [`samples`](/documentation/Evaluations/SampleGenerator/samples) to retrieve the full dataset (initial + generated), or
[`invalidSamples`](/documentation/Evaluations/SampleGenerator/invalidSamples) to see samples the validator rejected.
