Struct actix::sync::SyncContext

pub struct SyncContext<A> where
    A: Actor<Context = SyncContext<A>>,  { /* fields omitted */ }

Sync actor execution context. This is used instead of impl Actor for your Actor instead of Context, if you intend this actor to run in a SyncArbiter.

Unlike Context, an Actor that uses a SyncContext can not be stopped by calling stop or terminate: Instead, these trigger a restart of the Actor. Similar, returning false from fn stopping can not prevent the restart or termination of the Actor.

Example

use actix::prelude::*;



struct SyncActor;

impl Actor for SyncActor {
    // It's important to note that you use "SyncContext" here instead of "Context".
    type Context = SyncContext<Self>;
}

Trait Implementations

impl<A> ActorContext for SyncContext<A> where
    A: Actor<Context = Self>, 

fn stop(&mut self)

Stop the current Actor. SyncContext will stop the existing Actor, and restart a new Actor of the same type to replace it.

fn terminate(&mut self)

Terminate the current Actor. SyncContext will terminate the existing Actor, and restart a new Actor of the same type to replace it.

fn state(&self) -> ActorState

Get the Actor execution state.

impl<A, M> ToEnvelope<A, M> for SyncContext<A> where
    A: Actor<Context = Self> + Handler<M>,
    M: Message + Send + 'static,
    M::Result: Send, 

fn pack(msg: M, tx: Option<SyncSender<M::Result>>) -> Envelope<A>

Pack message into suitable envelope
