pub trait TopicDescription {

Expand description

TopicDescription trait — base interface for anything a DataReader (typed via T) can obtain samples from.

Spec reference: OMG DDS 1.4 §2.2.2.3.1 “TopicDescription is the most abstract description of a topic. It encapsulates the information that is common to all the kinds of topic that can be used: Topic, ContentFilteredTopic, MultiTopic.”

The trait is object-safe — we want to be able to return it as &dyn TopicDescription from lookup_topicdescription and find_topic.

Required Methods§

Source

fn get_type_name(&self) -> &str

Type name (e.g. "std_msgs::msg::String"). Spec §2.2.2.3.1 get_type_name.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
