Trait Handler 

pub trait Handler<M: 'static + Send>: Actor {
    type Result: Send;

    // Required method
    fn handle<'life0, 'life1, 'async_trait>(
        &'life0 mut self,
        message: M,
        context: &'life1 mut Context<Self>,
    ) -> Pin<Box<dyn Future<Output = Self::Result> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Handler handles a certain type of message asyncronously.

Example

use async_trait::async_trait;
use atomic_actor::*;

struct AddOne;

impl Actor for AddOne {
    type Context = Context<Self>;
}

#[async_trait]
impl Handler<i32> for AddOne {
    type Result = i32;

    async fn handle(&mut self, message: i32, _: &mut Context<Self>) -> i32 {
       message + 1
    }
}

#[tokio::main]
async fn main() {
   let addr = AddOne.start();
   assert_eq!(addr.send(1).unwrap().await, 2);
}

Required Associated Types

type Result: Send

The result of the handler. Must be Send.

Required Methods

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

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

Handles the message.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
