Missing usage examples

[busstoptaktik]

As yaml_rust seems unmaintained, I'm considering switching to minimal-yaml. But as a relative newbie to Rust, I have problems figuring out how to access elements in the minimal-yaml representation.

With yaml_rust, I do stuff like this:

    let txt = std::fs::read_to_string("src/simple.yml").unwrap();
    let docs = YamlLoader::load_from_str(&txt).unwrap();

    // Sequence
    let steps = docs[0]["recipe"]["steps"].as_vec().unwrap();
    for s in steps {
        ...
    }

    // Mapping
    let globals = docs[0]["recipe"]["globals"].as_hash().unwrap();
    let iter = globals.iter();
    for (arg, val) in iter {
        ...
    }

With minimal-yaml, I can get as far as:

    let txt = std::fs::read_to_string("src/simple.yml").unwrap();
    let rep = parse(&txt).unwrap();

    // This works as expected
    println!("{:?}", rep);

But I cannot figure out how to loop/search the representation with minimal-yaml. To get me started, a few usage examples in the documentation would be very helpful.

    // But how can I do this properly?
    for r in &rep {
        println!("r: {:?}", dd);
    }
