Implementations

impl ClusterInfo

pub fn new_with_invalid_keypair(contact_info: ContactInfo) -> Self

Without a valid keypair gossip will not function. Only useful for tests.

pub fn refresh_vote(&self, vote: Transaction, vote_slot: Slot)

pub fn send_vote(
    &self,
    vote: &Transaction,
    tpu: Option<SocketAddr>
) -> Result<(), Error>

pub fn get_votes(
    &self,
    cursor: &mut Cursor
) -> (Vec<CrdsValueLabel>, Vec<Transaction>)

Returns votes inserted since the given cursor.

pub fn get_accounts_hash_for_node<F, Y>(
    &self,
    pubkey: &Pubkey,
    map: F
) -> Option<Y> where
    F: FnOnce(&Vec<(Slot, Hash)>) -> Y, 

pub fn get_snapshot_hash_for_node<F, Y>(
    &self,
    pubkey: &Pubkey,
    map: F
) -> Option<Y> where
    F: FnOnce(&Vec<(Slot, Hash)>) -> Y, 

pub fn get_node_version(&self, pubkey: &Pubkey) -> Option<Version>

pub fn all_rpc_peers(&self) -> Vec<ContactInfo>

all validators that have a valid rpc port regardless of shred_version.

pub fn gossip_peers(&self) -> Vec<ContactInfo>

pub fn all_tvu_peers(&self) -> Vec<ContactInfo>

all validators that have a valid tvu port regardless of shred_version.

pub fn tvu_peers(&self) -> Vec<ContactInfo>

all validators that have a valid tvu port and are on the same shred_version.

pub fn repair_peers(&self, slot: Slot) -> Vec<ContactInfo>

all tvu peers with valid gossip addrs that likely have the slot being requested

pub fn sorted_retransmit_peers_and_stakes(
    &self,
    stakes: Option<&HashMap<Pubkey, u64>>
) -> (Vec<ContactInfo>, Vec<(u64, usize)>)

pub fn shuffle_peers_and_index(
    id: &Pubkey,
    peers: &[ContactInfo],
    stakes_and_index: &[(u64, usize)],
    seed: [u8; 32]
) -> (usize, Vec<(u64, usize)>)

Return sorted Retransmit peers and index of Self.id() as if it were in that list

pub fn tpu_peers(&self) -> Vec<ContactInfo>

compute broadcast table

pub fn retransmit_to(
    peers: &[&ContactInfo],
    packet: &Packet,
    s: &UdpSocket,
    forwarded: bool
)

retransmit messages to a list of nodes

Remarks

We need to avoid having obj locked while doing a io, such as the send_to

pub fn gossip(
    self: Arc<Self>,
    bank_forks: Option<Arc<RwLock<BankForks>>>,
    sender: PacketSender,
    gossip_validators: Option<HashSet<Pubkey>>,
    exit: Arc<AtomicBool>
) -> JoinHandle<()>

randomly pick a node and ask them for updates asynchronously

pub fn gossip_contact_info(
    id: &Pubkey,
    gossip: SocketAddr,
    shred_version: u16
) -> ContactInfo

pub fn gossip_node(
    id: &Pubkey,
    gossip_addr: &SocketAddr,
    shred_version: u16
) -> (ContactInfo, UdpSocket, Option<TcpListener>)

An alternative to Spy Node that has a valid gossip address and fully participate in Gossip.

pub fn spy_node(
    id: &Pubkey,
    shred_version: u16
) -> (ContactInfo, UdpSocket, Option<TcpListener>)

A Node with dummy ports to spy on gossip via pull requests
