Build URLs with custom query params

query.rs

extern mod extra;

use extra::url::Url;

fn main() {
    let params = ~[(~"test", ~"value")];
    let mut url: Url = FromStr::from_str("http://www.example.com").unwrap();

    // url.query is extra::url::Query
    // which is a type = ~[(~str, ~str)]
    url.query.push_all(params);

    // prints http://www.example.com?test=value
    println(url.to_str());
