Adding actix-web v2.0.0 to dependencies
Adding actix-rt v1.1.1 to dependencies
PS work/todo>
Doesn't it take a minute? Rust has the impression that related tools work lightly.
It will be added to Cargo.toml as follows.
Cargo.toml
[dependencies]
actix-web = "2.0.0"
actix-rt = "1.1.1"
p.192 src/main.rs
src/main.rs
use actix_web::{get, App, HttpResponse, HttpServer};
#[get("/")]
async fn index() -> Result<HttpResponse, actix_web::Error> {
let response_body = "Hello world!";
Ok(HttpResponse::Ok().body(response_body))
}
#[actix_rt::main]
async fn main() -> Result<(), actix_web::Error> {
HttpServer::new(move || App::new().service(index))
.bind("0.0.0.0:8008")?
.run()
.await?;
Ok(())
}
The amount of description that is not painful. There are functions such as ʻasync` that are appreciated when building a full-scale service. As a preliminary survey, the following code was also experimented with Sinatra (Ruby). It's incredibly short.
myapp.rb
require 'sinatra'
set :bind, '0.0.0.0'
get '/' do
'Hello world!'
end
p.192 cargo run
After compiling 197 modules, the service starts.

You can reach this point in 10 minutes after doing cargo new to do (of course, there are differences in the specifications of the PC used). With this lightness, even when the REST API is released, you can earn enough work response speed.
