The following article is worth studying:

Iron is a Web framework built on hyper. hyper is an http library fully written by Rust. Therefore, Iron is equivalent to Tomcat/Jetty in Java,

Cowboy is for Erlang. The following describes how to use Iron to write a WebServer. When a user accesses http: // localhost: 3000 in the address bar of a browser,

The browser returns HelloWorld.

It's easy, just three steps:

1) install Rust. Refer to my series of articles: http://blog.csdn.net/ubuntu64fan/article/details/47863935

2) create a HelloWorld project. Refer to my series of articles: http://blog.csdn.net/ubuntu64fan/article/details/48370617

3) Modify hello_world/Cargo. toml and add the following content:

[dependencies]iron = "*"

Modify hello_world/src/main. rs with the following content:

extern crate iron;use iron::prelude::*;use iron::status;fn main() {    fn hello_world(_: &mut Request) -> IronResult<Response> {        Ok(Response::with((status::Ok, "Hello World!")))    }    Iron::new(hello_world).http("localhost:3000").unwrap();    println!("On 3000");}

Then run the compilation command below hello_world:

# cargo build# cargo run

Running 'target/debug/hello_world'

Open the browser and check: localhost: 3000

Hello World!

Several terminologies of Rust:

Cargo: The construction tool of the rust language. It is very image-oriented. It refers to trucks.

Crate: equivalent to java jar package, so of c/c ++. Wicker boxes. Various wicker boxes are installed in the van.

Rustc: The rust compiler.
