How to do it...

Perform the following steps to implement this recipe:

1. In src/main.rs, we are going to add the imports first:

#[macro_use]extern crate actix_web;use actix_web::{    guard, http::Method, middleware, web, App, HttpResponse, HttpServer,};use serde_derive::{Deserialize, Serialize};use std::env;

2. Next, let's create some handler functions along with a serializable JSON type. Add the following code to src/main.rs:

#[derive(Debug, Clone, Serialize, Deserialize)]struct Bookmark {    id: i32,    url: String,}#[get("by-id/{id}")]fn bookmarks_by_id(id: web::Path<(i32)>) -> HttpResponse {    let bookmark = Bookmark {        id: *id,        url: "https://blog.x5ff.xyz".into(),    };    HttpResponse::Ok().json(bookmark)}fn echo_bookmark(bookmark: web::Json<Bookmark>) ...
