What is the purpose of pending::ConsensusDataProvider?

What is the purpose of a struct that implements pending::ConsensusDataProvider? I know that the template uses an AuraPendingConsensusDataProvider. What is it for? When implementing BABE, should I write one? If so, what should the create_digest method return (i.e. what should go in the digest)?
