[−][src]Trait jsonrpc_pubsub::PubSubMetadata
Metadata extension for pub-sub method handling.
NOTE storing PubSubMetadata
(or rather storing Arc<Session>
) in
any other place outside of the handler will prevent unsubscribe
methods
to be called in case the Session
is dropped (i.e. transport connection is closed).
Required methods
fn session(&self) -> Option<Arc<Session>>
Returns session object associated with given request/client.
None
indicates that sessions are not supported on the used transport.
