Hands-On Microservices with Rust

Using the server with actors

Import all necessary types for a server. It's worth noting only those with which you're unfamiliar:

use actix::{Actor, Addr};use actix::sync::SyncArbiter;

Addr is an address of an actor. SyncArbiter is a synchronous event-loop controller that handles every message synchronously. We need it for resizing actors. Also, add the actors module and import all the types we declared in the submodules:

mod actors;use self::actors::{    count::{Count, CountActor},    log::{Log, LogActor},    resize::{Resize, ResizeActor},};

We need a shared state to keep all the addresses of the actors that we'll use to handle requests:

#[derive(Clone)]struct State {    resize: Addr<ResizeActor>,    count: Addr<CountActor>,    log: Addr<LogActor>,}
