Handles incoming RPCs for a specific entity instance.

Each entity instance has one handler that processes all incoming messages. The handler is created by Entity::spawn and lives until the entity is reaped (idle timeout) or the runner shuts down.

Required Methods

fn handle_request<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, tag: &'life1 str, payload: &'life2 [u8], headers: &'life3 HashMap<String, String>, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>, ClusterError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Handle an incoming request. Returns serialized response bytes.

Provided Methods

fn handle_stream<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, tag: &'life1 str, payload: &'life2 [u8], headers: &'life3 HashMap<String, String>, ) -> Pin<Box<dyn Future<Output = Result<Pin<Box<dyn Stream<Item = Result<Vec<u8>, ClusterError>> + Send>>, ClusterError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Handle a streaming request. Returns a stream of serialized chunks.

Default implementation wraps handle_request as a single-item stream.

fn on_idle<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

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

Called when the entity is about to be reaped (idle timeout). Return true to keep alive, false to allow reaping.
