Some extensions to the zenoh::Session

This API has been marked as unstable: it works as advertised, but it may be changed in a future release.

Required Methods

fn declare_publication_cache<'a, 'b, 'c, TryIntoKeyExpr>( &'a self, pub_key_expr: TryIntoKeyExpr, ) -> PublicationCacheBuilder<'a, 'b, 'c>

where TryIntoKeyExpr: TryInto<KeyExpr<'b>>, <TryIntoKeyExpr as TryInto<KeyExpr<'b>>>::Error: Into<Error>,

👎Deprecated: Use AdvancedPublisher and AdvancedSubscriber instead.

Declare a PublicationCache.

This API has been marked as unstable: it works as advertised, but it may be changed in a future release.

Examples:

use zenoh_ext::SessionExt;
use zenoh_config::ModeDependentValue::Unique;


let mut config = zenoh::Config::default();
config.timestamping.set_enabled(Some(Unique(true)));
let session = zenoh::open(config).await.unwrap();
let publication_cache = session.declare_publication_cache("key/expression").await.unwrap();
tokio::task::spawn(async move {
    publication_cache.key_expr();
}).await;

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
