Initialize a peer set, using a network config, inbound_service, and latest_chain_tip.

The peer set abstracts away peer management to provide a [tower::Service] representing “the network” that load-balances requests over available peers. The peer set automatically crawls the network to find more peer addresses and opportunistically connects to new peers.

Each peer connection’s message handling is isolated from other connections, unlike in zcashd. The peer connection first attempts to interpret inbound messages as part of a response to a previously-issued request. Otherwise, inbound messages are interpreted as requests and sent to the supplied inbound_service.

Wrapping the inbound_service in [tower::load_shed] middleware will cause the peer set to shrink when the inbound service is unable to keep up with the volume of inbound requests.

Use NoChainTip to explicitly provide no chain tip receiver.

In addition to returning a service for outbound requests, this method returns a shared AddressBook updated with last-seen timestamps for connected peers. The shared address book should be accessed using a blocking thread, to avoid async task deadlocks.

Panics

If config.config.peerset_initial_target_size is zero. (zebra-network expects to be able to connect to at least one peer.)
