Struct nsq_client::Connection

pub struct Connection { /* fields omitted */ }

Tcp Connection to NSQ system.

Tries to connect to nsqd early as started:

Examples

use actix::prelude::*;
use nsq_client::Connection;

fn main() {
    let sys = System::new("consumer");
    Supervisor::start(|_| Connection::new(
        "test", // <- topic
        "test", // <- channel
        "0.0.0.0:4150", // <- nsqd tcp address
        None, // <- config (Optional)
        None, // <- secret used by Auth
        Some(1) // <- RDY setting for the Connection
    ));
    sys.run();
}

Methods

impl Connection

pub fn new<S: Into<String>>(
    topic: S,
    channel: S,
    addr: S,
    config: Option<Config>,
    secret: Option<String>,
    rdy: Option<u32>
) -> Connection

Return a Tcp Connection to nsqd.

• topic - Topic String
• channel - Channel String
• addr - Tcp address of nsqd
• config - Optional Config
• secret - Optional String used to autenticate to nsqd
• rdy - Optional initial RDY setting

Trait Implementations

impl Default for Connection

fn default() -> Connection

Returns the "default value" for a type.

impl Actor for Connection

type Context = Context<Self>

Actor execution context type

fn started(&mut self, ctx: &mut Context<Self>)

Method is called when actor get polled first time.

fn stopping(&mut self, ctx: &mut Self::Context) -> Running

Method is called after an actor is in Actor::Stopping state. There could be several reasons for stopping. Context::stop get called by the actor itself. All addresses to current actor get dropped and no more evented objects left in the context.

fn stopped(&mut self, ctx: &mut Self::Context)

Method is called after an actor is stopped, it can be used to perform any needed cleanup work or spawning more actors. This is final state, after this call actor get dropped.

fn start(self) -> Addr<Self> where
    Self: Actor<Context = Context<Self>>, 

Start new asynchronous actor, returns address of newly created actor.

fn start_default() -> Addr<Self> where
    Self: Actor<Context = Context<Self>> + Default, 

Start new asynchronous actor, returns address of newly created actor.

fn create<F>(f: F) -> Addr<Self> where
    F: FnOnce(&mut Context<Self>) -> Self + 'static,
    Self: Actor<Context = Context<Self>>, 

Use create method, if you need Context object during actor initialization.

impl Supervised for Connection

fn restarting(&mut self, ctx: &mut Self::Context)

Method called when supervisor restarting failed actor

impl Handler<Fin> for Connection

type Result = ()

The type of value that this handle will return

fn handle(&mut self, msg: Fin, ctx: &mut Self::Context)

Method is called for every message received by this Actor

impl Handler<Ready> for Connection

type Result = ()

The type of value that this handle will return

fn handle(&mut self, msg: Ready, _ctx: &mut Self::Context)

Method is called for every message received by this Actor

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

impl WriteHandler<Error> for Connection

fn error(&mut self, err: Error, _: &mut Self::Context) -> Running

Method is called when writer emits error.

fn finished(&mut self, ctx: &mut Self::Context)

Method is called when writer finishes.
