**Header:** `ClikaRT/compute/scope.h`

While alive, every op dispatched on the calling thread WAITS for completion before the dispatch call returns, and `stream` runs at most one task at a time, so the moment a dispatch returns, the result is ready ([`Stream::query_idle()`](./Stream.md#query_idle) is true). Deterministic, ideal for debugging / per-op stepping; it trades away the throughput that async pipelining buys. The stream's prior limit is restored on destruction. Open it only on a quiescent stream (synchronize first). Non-copyable, non-movable.

### SynchronousStreamScope(Stream) {#SynchronousStreamScope}

<div class="api-signature">

`explicit` **`SynchronousStreamScope`**(`const` [`Stream`](./Stream.md)`&` `stream`)

</div>

Enter: ops issued on `stream` from this thread run synchronously until the scope exits.
