Possibility #1
1.a.: Figure out how to perform a GET with Rust
Hyper
https://github.com/hyperium/hyper
1.b.: Print a response status
1.c.: Print the page body content
fn main() {
let client = Client::new();
let mut response = client.
get("url").
header(Connection::close()).send().unwrap();
let mut body = String::new();
response.read_to_string(&mut body).unwrap();
println!("Body: {}", body);
}1.d.: Save body into a local HTML file
pub fn write(path: &Path, body: &str) -> io::Result<()> {
let mut f = try!(File::create(path));
f.write_all(body.as_bytes())
}1.e. Use select.rs

What we can learn
- Iterator
- Struct | impl
- get the right modules
Possibility #2
Same as #1, except that we could use scraper
Scraper

Possibility #3 - From Scratch
