Step 2 - Create Service
=======================
For this example, we are going to create a simple Rust project that serves a static web page.
.. code:: bash
mkdir hello-world
cargo init
touch src/index.html
In ``index.html`` add:
.. code:: html
Hello World!
Hello World!
In ``main.rs`` add:
.. code:: rust
use hyper::service::{make_service_fn, service_fn};
use hyper::{body::Bytes, Body, Request, Response, Server};
use std::convert::Infallible;
use std::net::SocketAddr;
async fn handle(_req: Request) -> Result, Infallible> {
Ok(Response::new(Body::from(Bytes::from_static(
include_bytes!("index.html"),
))))
}
#[tokio::main]
async fn main() {
// Construct our SocketAddr to listen on...
let addr = SocketAddr::from(([0, 0, 0, 0], 80));
// And a MakeService to handle each connection...
let make_service = make_service_fn(|_conn| async { Ok::<_, Infallible>(service_fn(handle)) });
// Then bind and serve...
let server = Server::bind(&addr).serve(make_service);
// And run forever...
if let Err(e) = server.await {
eprintln!("server error: {}", e);
}
}
**That's it!** We now have the code for our service.
Let's build and run it!
.. code:: bash
# build the project
cargo build
# start the executable
target/debug/hello-world
Visit ``_ to see your running web page!
