 /// A workflow can be seen as a special type of [Virtual Object](https://docs.restate.dev/concepts/services#virtual-objects) with the following characteristics:
 /// 
-/// - Each workflow definition has a **`Run` handler** that implements the workflow logic.

 ///         - [Calls to other handlers](crate::context::ContextClient) implementing the activities
 /// - You can **submit a workflow** in the same way as any handler invocation (via SDK clients or Restate services, over HTTP or Kafka).
 /// - A workflow definition can implement other handlers that can be called multiple times, and can **interact with the workflow**:
 ///   - Query the workflow (get information out of it) by getting K/V state or awaiting promises that are resolved by the workflow.
 ///   - Signal the workflow (send information to it) by resolving promises that the workflow waits on.
 /// - Workflows have access to the [`WorkflowContext`](crate::context::WorkflowContext) and [`SharedWorkflowContext`](crate::context::SharedWorkflowContext), giving them some extra functionality, for example [Durable Promises](#signaling-workflows) to signal workflows.
-/// - The K/V state of the workflow is isolated to the workflow execution, and can only be mutated by the `Run` handler.
