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](zenoh) that allow opening a [Session](zenoh::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.
