Struct TopicListener 

pub struct TopicListener<T>
where
    T: Topicable,
{ /* private fields */ }

Listener attached to a Topic<T>.

Implementations

impl<T> TopicListener<T>

where T: Topicable,

pub fn new() -> Self

Creates a new TopicListener<T> with no callbacks registered.

Examples

use cyclonedds::TopicListener;

let listener = TopicListener::<Data>::new();

pub fn with_inconsistent_topic( self, callback: fn(&Topic<'_, '_, T>, InconsistentTopic), ) -> Self

Sets a callback for the InconsistentTopic status event.

The callback receives an InconsistentTopic metadata struct.

Fired when a remote topic is discovered with the same name but an incompatible type or QoS.

Examples

use cyclonedds::listener::TopicListener;

let listener =
    TopicListener::<Data>::new().with_inconsistent_topic(|topic, inconsistent_topic| {
        println!("inconsistent topic: {inconsistent_topic:?}");
    });

impl<T> Clone for TopicListener<T>

where T: Topicable + Clone,

fn clone(&self) -> TopicListener<T>

impl<T> Debug for TopicListener<T>

where T: Topicable + Debug,

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

Formats the value using the given formatter.

impl<T> Default for TopicListener<T>

where T: Topicable,

fn default() -> Self

Returns the “default value” for a type.
