Struct zenoh_flow_nodes::prelude::Context

pub struct Context { /* private fields */ }

The Context structure provides information about the data flow and the Zenoh-Flow runtime.

In particular, it allows accessing:

• the name of the data flow,
• the instance id of this instance of the data flow,
• the runtime id of the Zenoh-Flow runtime managing the node.

Implementations

impl Context

pub fn new( flow_name: Arc<str>, instance_id: InstanceId, runtime_id: RuntimeId ) -> Self

Creates a new node Context.

pub fn name(&self) -> &str

Returns the name of the data flow.

Note all instances of the same data flow will share the same name.

pub fn instance_id(&self) -> &InstanceId

Returns the unique identifier of this instance of the data flow.

pub fn runtime_id(&self) -> &RuntimeId

Returns the unique identifier of the Zenoh-Flow runtime managing the node.

Note that, for the same instance, different nodes might return different runtime identifier if they are running on different Zenoh-Flow runtimes.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Context

fn fmt(&self, f: &mut Formatter<'_>) -> Result
