The original implementation of Attributes had an iter method but it did not implement FromIterator for &Attributes, making it so you couldn't use for (key, value) in &attributes and had to use for (key, value) in attributes.iter(). This changes that.
Additionally, Extend is a nice quality of life trait for containers so it's implemented here.
