Backend defines the data retrieval methods to serve remote requests and the callback methods to invoke on remote deliveries.

Packet represents a p2p message in the `snap` protocol.

SyncPeer abstracts out the methods required for a peer to be synced against with the goal of allowing the construction of mock peers without the full blown networking.

Handler is a callback to invoke from an outside runner after the boilerplate exchanges have passed.

TrieNodePathSet is a list of trie node paths to retrieve.
