### stream {#stream}

<div class="api-signature">

`std::optional<`[`Stream`](../Stream.md)`>` **`stream`**

</div>

The stream this node runs on. Unset = a new asynchronous stream, created for this node (a CPU stream when the node's model device is unknown to the executor; the serving pipeline sets each node's stream from its model). Pass `Stream::default_stream(device)` only to opt into synchronous execution. A pipeline warns when steps share a stream or run on a synchronous one.
