Rust: Load a file

load_file.rs

fn load(filename: ~str) -> ~[~str] {

    // The simple way:
    // let read_result = io::file_reader(~path::Path(filename));

    let read_result: Result<@Reader, ~str>;
    read_result = io::file_reader(~path::Path(filename));

    if read_result.is_ok() {
        let file = read_result.unwrap();
        return file.read_lines();
    }

    println(fmt!("Error reading file: %?", read_result.unwrap_err()));
    return ~[];
}

fn main() {
    let contents = load(~"myfile.txt");
    println(fmt!("%?", contents));
}
