Struct rustdds::Topic

pub struct Topic { /* private fields */ }

DDS Topic

DDS Specification, Section 2.2.1.2 Conceptual outline:

Topic objects conceptually fit between publications and subscriptions. Publications must be known in such a way that subscriptions can refer to them unambiguously. A Topic is meant to fulfill that purpose: it associates a name (unique in the > domain), a data-type, and QoS related to the data itself.

Topics can be created (or found) using a DomainParticipant.

Examples

use rustdds::dds::DomainParticipant;
use rustdds::dds::qos::QosPolicyBuilder;
use rustdds::dds::Topic;
use rustdds::dds::data_types::TopicKind;

let domain_participant = DomainParticipant::new(0).unwrap();
let qos = QosPolicyBuilder::new().build();
let topic = domain_participant
      .create_topic("some_topic".to_string(), "SomeType".to_string(), &qos, TopicKind::WithKey)
      .unwrap();

Implementations

impl Topic

pub fn kind(&self) -> TopicKind

Gets Topics TopicKind

Examples

use rustdds::dds::data_types::TopicKind;

let topic = domain_participant
    .create_topic("some_topic".to_string(), "SomeType".to_string(), &qos, TopicKind::WithKey)
    .unwrap();
assert_eq!(topic.kind(), TopicKind::WithKey);
