Expand description

Parses a repeated proto struct into a map.

The method assumes that we have a BTreeMap<K, V> field that we serialized as Vec<T> into protobuf, where T consists of a K::Proto and V::Proto field. The k and v function are getters to project T into the key and value protobuf components, which are individually decoded into K and V.
