Struct nsq_client::Backoff

pub struct Backoff;

Allows Consumer to set Connection on backoff state

Examples

use actix::prelude::*;
use nsq_client::{Subscribe, Connection, Backoff, OnBackoff, OnResume, InFlight, Ready};
struct Consumer{
    conn: Addr<Connection>,
    backoff: bool,
};

impl Actor for Consumer {
    type Context = Context<Self>;
    fn started(&mut self, _: &mut Self::Context) {
        self.subscribe::<OnBackoff>(ctx, self.0.clone());
        self.subscribe::<OnResume>(ctx, self.0.clone());
        self.subscribe::<InFlight>(ctx, self.0.clone());
        self.conn.do_send(Ready(10));
        self.conn.do_send(Backoff);
    }
}

impl Handler<OnBackoff> for Consumer {
    type Result = ();
    fn handle(&mut self, msg: OnBackoff, _: &mut Self::Context) {
        println!("Connection in Backoff");
        self.backoff = true;
    }
}

impl Handler<OnResume> for Consumer {
    type Result = ();
    fn handle(&mut self, msg: OnResume, _: &mut Self::Context) {
        println!("Connection resuming from backoff");
        self.backoff = false;
    }
}

impl Handler<OnInflight> for Consumer {
    type Result = ();
    fn handle(&mut self, msg: OnInFlight, _: &mut Self::Context) {
        match msg.0 {
            0 => { println!("backoff state: {}", self.backoff) },
            1 => { println!("resuming from backoff") },
            _ => { println!("throttle") },
        }
    }
}

Trait Implementations

impl Message for Backoff

type Result = ()

The type of value that this message will resolved with if it is successful.

impl Handler<Backoff> for Connection

type Result = ()

The type of value that this handle will return

fn handle(&mut self, _msg: Backoff, ctx: &mut Self::Context)

Method is called for every message received by this Actor
