where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Handler<Keepalive> for KeepaliveSupervisor

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, message: Keepalive, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handle the next M-typed message.

fn message_status_reporting() -> MessageStatusReporting
