Trying to match String content inside an Enum.

match_string.rs

// works, but ugly
fn check1(s: Option<String>) {
    match s {
        Some(t) => {
            match t.as_slice() {
                "test" => println!("yep"),
                _ => println!("nope")
            }
        },
        None => println!("nope")
    }
}

// fails to compile
fn check2(s: Option<String>) {
    match s {
        Some("test") => println!("yep"),
        _ => println!("nope")
    }
}

fn main() {
    check2(Some("test".to_str()));
    check2(Some("test2".to_str()));
    check2(None);
}
