AddressBookUpdater

zebra_network::address_book_updater

Struct AddressBookUpdater 

Source 
pub struct AddressBookUpdater;
Expand description

The AddressBookUpdater hooks into incoming message streams for each peer and lets the owner of the sender handle update the address book. For example, it can be used to record per-connection last-seen timestamps, or add new initial peers to the address book.

It also serves AddressBookRequests through a [Buffer]-wrapped AddressBookService, which shares a single ordered request queue with the change events. This makes compound operations like AddressBookRequest::NextReconnectPeer atomic by construction.

Implementations§

Source§

impl AddressBookUpdater

Source

pub fn spawn( config: &Config, local_listener: SocketAddr, ) -> (Arc<Mutex<AddressBook>>, Receiver<BanList>, AddressBookChangeSender, Buffer<BoxService<AddressBookRequest, AddressBookResponse, BoxError>, AddressBookRequest>, Receiver<AddressMetrics>, JoinHandle<Result<(), BoxError>>)

Spawn a new AddressBookUpdater task, updating a new AddressBook configured with Zebra’s actual local_listener address.

Returns handles for:

  • the address book, which should only be used for hot reads,
  • a watch channel for the ban list,
  • the transmission channel for address book update events,
  • a buffered service for address book requests,
  • a watch channel for address book metrics, and
  • the address book updater task join handle.

The task exits with an error when all the returned AddressBookChangeSenders and AddressBookServices are closed.

Source

pub fn spawn_with_address_book( address_book: AddressBook, channel_size: usize, ) -> (Arc<Mutex<AddressBook>>, Receiver<BanList>, AddressBookChangeSender, Buffer<BoxService<AddressBookRequest, AddressBookResponse, BoxError>, AddressBookRequest>, Receiver<AddressMetrics>, JoinHandle<Result<(), BoxError>>)

Spawn a new AddressBookUpdater task for an existing address_book, using channel_size for the update channel and service buffer.

See AddressBookUpdater::spawn for details.
