The HelloWorld web version of Rust language

The following article is worth studying carefully:

Iron is a web framework, built on hyper, and hyper is a completely HTTP library written with Rust. Therefore, iron is equivalent to Tomcat/jetty in Java,

Cowboy to Erlang. Use iron to write a webserver, very simple, when users access http://localhost:3000 in the browser address bar,

Browser return: HelloWorld.

Very simple, just 3 steps:

1) Install rust. Reference to my series of articles: http://blog.csdn.net/ubuntu64fan/article/details/47863935

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

3) Modify HELLO_WORLD/CARGO.TOML, add the following content:

[Dependencies]
Iron = "*"

To modify the hello_world/src/main.rs, the full contents are as follows:

extern crate Iron;

Use iron::p relude::*;
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 compile command under hello_world/:

# Cargo Build
# cargo Run

Running ' Target/debug/hello_world '

Open Browser, view: localhost:3000

Hello world!

Rust Several terms:

Cargo:rust language Construction tools, very image, truck, put things into the meaning.

Crate: Java-equivalent jar pack, and C + + so. A wicker box with various wicker boxes in the van.

Compiler for Rustc:rust language.
