) -> Result<ClientState<HeaderIdOf<SelfChain>, HeaderIdOf<PeerChain>>, Error>

Expand description

Read best blocks from given client.

This function assumes that the chain that is followed by the self_client has bridge GRANDPA pallet deployed and it provides best_finalized_header_id_method_name runtime API to read the best finalized Bridged chain header.

The value of actual_best_finalized_peer_at_best_self will always match the best_finalized_peer_at_best_self.
