Derive macros for actix actors.

Usage

use actix_derive::{Message, MessageResponse};

#[derive(MessageResponse)]
struct Added(usize);

#[derive(Message)]
#[rtype(Added)]
struct Sum(usize, usize);

fn main() {}

This code expands into following code:

use actix::{Actor, Context, Handler, System};
use actix_derive::{Message, MessageResponse};

#[derive(MessageResponse)]
struct Added(usize);

#[derive(Message)]
#[rtype(Added)]
struct Sum(usize, usize);

#[derive(Default)]
struct Adder;

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

impl Handler<Sum> for Adder {
    type Result = <Sum as actix::Message>::Result;
    fn handle(&mut self, msg: Sum, _: &mut Self::Context) -> Added {
        Added(msg.0 + msg.1)
    }
}

fn main() {}
