Expand description
Actix Web is a powerful, pragmatic, and extremely fast web framework for Rust.
§Examples
use actix_web::{get, web, App, HttpServer, Responder};
#[get("/hello/{name}")]
async fn greet(name: web::Path<String>) -> impl Responder {
    format!("Hello {}!", name)
}
#[actix_web::main] // or #[tokio::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        App::new().service(greet)
    })
    .bind(("127.0.0.1", 8080))?
    .run()
    .await
}§Documentation & Community Resources
In addition to this API documentation, several other resources are available:
To get started navigating the API docs, you may consider looking at the following pages first:
- 
App: This struct represents an Actix Web application and is used to configure routes and other common application settings.
- 
HttpServer: This struct represents an HTTP server instance and is used to instantiate and configure servers.
- 
web: This module provides essential types for route registration as well as common utilities for request handlers.
- 
HttpRequestandHttpResponse: These structs represent HTTP requests and responses and expose methods for creating, inspecting, and otherwise utilizing them.
