pub fn encode_document<'a, S: AsRef<str> + 'a, W: Write + ?Sized, D: IntoIterator<Item = (&'a S, &'a Bson)>>(
    writer: &mut W, 
    doc: D
) -> EncoderResult<()>

Attempt to encode a Document into a byte stream.

Can encode any type which is iterable as (key: &str, value: &Bson) pairs, which generally means most maps.
