A bit minor, and I'm not a real Rust programmer, but:

The string argument for `.expect` should be phrased in a more positive manner in terms of what is expected, since failure will cause a panic. So, something like:

    let key = CString::new(key).expect("boolean key should be valid CString");

which would produce, e.g.,

    panic: boolean key should be valid CString: ... details of key ...

A similar rule applies to the later `.expect`.
