This crate exposes the structures driving the execution of a data flow: the [Runtime] and the [DataFlowInstance].
If the feature zenoh is enabled (it is by default), this crate additionally re-exports the structures from
Zenoh that allow opening a Session asynchronously.
Users interested in exposing a Zenoh-Flow runtime should find everything in the [Runtime] and [RuntimeBuilder].
Users interested in fetching the state of a data flow instance should look into the [DataFlowInstance],
[InstanceState] and [InstanceStatus] structures. These structures are leveraged by the zfctl command line tool.
