# A Beginner Guide to Rust HTTP Client Libraries

This repository contains an example of how to use HTTP client libraries in Rust.

We will start with low level library called `Hyper` and move up with high-level

library called `reqwest`.

So, let's start with `GET` request.

# GET Request

Below is an example code on how to perform HTTP `GET` request using the

`hyper` library

```rust

extern crate hyper;

use hyper::body::HttpBody as _;

use hyper::Client;

use tokio::io::{stdout, AsyncWriteExt as _};

#[tokio::main]

async fn main() -> Result<(), Box> {

    // This is where we will setup our HTTP client requests.

    println!("Hello?");

    // Still inside `async fn main`...

    let client = Client::new();

    // Parse an `http::Uri`...

    let uri = "http://httpbin.org/ip".parse()?;

    // Await the response...

    let mut resp = client.get(uri).await?;

    println!("Response: {}", resp.status());

    // And now...

    while let Some(chunk) = resp.body_mut().data().await {

        stdout().write_all(&chunk?).await?;

    }

    Ok(())

}

```

Maybe you are beginner like me and have the following questions:

1. What is `#[tokio::main]` ? Why is there?

2. Why returns `Result<(), Box>` ?

See you next time.
