pub struct MatchingStatus { /* private fields */ }

A struct that indicates if there exist entities matching the key expression.

Examples

let session = zenoh::open(zenoh::Config::default()).await.unwrap();
let publisher = session.declare_publisher("key/expression").await.unwrap();
let matching_subscribers: bool = publisher
    .matching_status()
    .await
    .unwrap()
    .matching();
