Struct PingPongActor

pub struct PingPongActor { /* private fields */ }

A PingPong actor that can play the PingPong game by sending messages around.

Trait Implementations

impl Actor for PingPongActor

type Params = PingPongActorParams

The type of initialization parameters accepted by this actor.

fn new<'async_trait>( params: Self::Params, ) -> Pin<Box<dyn Future<Output = Result<Self, Error>> + Send + 'async_trait>>

where Self: 'async_trait,

Creates a new actor instance given its instantiation parameters.

fn handle_undeliverable_message<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Instance<Self>, undelivered: Undeliverable<MessageEnvelope>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

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

Default undeliverable message handling behavior.

fn init<'life0, 'life1, 'async_trait>( &'life0 mut self, _this: &'life1 Instance<Self>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

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

Initialize the actor, after the runtime has been fully initialized. Init thus provides a mechanism by which an actor can reliably and always receive some initial event that can be used to kick off further (potentially delayed) processing.

fn spawn<'life0, 'async_trait>( cap: &'life0 (impl 'async_trait + CanSpawn), params: Self::Params, ) -> Pin<Box<dyn Future<Output = Result<ActorHandle<Self>>> + Send + 'async_trait>>

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

Spawn a child actor, given a spawning capability (usually given by Instance). The spawned actor will be supervised by the parent (spawning) actor.

fn spawn_detached<'async_trait>( params: Self::Params, ) -> Pin<Box<dyn Future<Output = Result<ActorHandle<Self>, Error>> + Send + 'async_trait>>

where Self: 'async_trait,

Spawns this actor in a detached state, handling its messages in a background task. The returned handle is used to control the actor’s lifecycle and to interact with it.

fn spawn_server_task<F>(future: F) -> JoinHandle<F::Output>

where F: Future + Send + 'static, F::Output: Send + 'static,

This method is used by the runtime to spawn the actor server. It can be used by actors that require customized runtime setups (e.g., dedicated actor threads), or want to use a custom tokio runtime.

fn handle_supervision_event<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, _this: &'life1 Instance<Self>, _event: &'life2 ActorSupervisionEvent, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>

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

Handle actor supervision event. Return `Ok(true)`` if the event is handled here.

impl Binds<PingPongActor> for PingPongActor

fn bind(ports: &Ports<Self>)

Bind ports in this actor.

impl Debug for PingPongActor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Handler<PingPongMessage> for PingPongActor

fn handle<'life0, 'life1, 'async_trait>( &'life0 mut self, cx: &'life1 Context<'_, Self>, __arg2: PingPongMessage, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Handles the PingPong Message. It will send the message to th actor specified in the PingPongMessage if TTL > 0. And deliver a true to the done port if TTL = 0. It also panics if TTL == 66 for testing purpose.

impl Named for PingPongActor

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.
