# holoscan::AsynchronousEventState

> Make AsynchronousEventState available to the holoscan namespace.

Make [AsynchronousEventState](asynchronouseventstate) available to the holoscan namespace.

```cpp showLineNumbers={false}
enum class holoscan::AsynchronousEventState
```

This enum is used for controlling and querying the state of asynchronous conditions. Moving it to the holoscan namespace improves usability when working with async operators. See Operator::async\_condition() for accessing the internal condition to control execution timing.
