Trait Implementations

impl Actor for RequestHandler

type Event = RequestHandlerEvent

The type of events this actor can broadcast to subscribers.

type Message = RequestHandlerMessage

The type of messages this actor accepts.

type Response = RequestHandlerResponse

The type returned by the actor in response to each message.

Called once before the actor begins processing messages.

fn drain_timeout() -> Duration

Maximum time to spend processing critical messages during shutdown before dropping them.

fn startup_timeout() -> Option<Duration>

Maximum time to wait for pre_start to complete; None disables the startup timeout.

fn stop_timeout() -> Option<Duration>

Maximum time a parent waits for this actor to acknowledge a stop request; None disables the stop timeout.

Returns the supervision strategy applied when this actor fails at startup.

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

Called after all children have stopped and the actor is fully shut down. Override for final cleanup.

fn from_response(_response: Self::Response) -> Result<Self::Event, Error>

Maps a handler response to an event; call explicitly when you need that conversion.

impl BorshDeserialize for RequestHandler

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>
