Implementations

impl CrdsGossip

pub fn process_push_message(
    &mut self,
    from: &Pubkey,
    values: Vec<CrdsValue>,
    now: u64
) -> HashSet<Pubkey>

process a push message to the network Returns unique origins’ pubkeys of upserted values.

pub fn prune_received_cache<I>(
    &mut self,
    self_pubkey: &Pubkey,
    origins: I,
    stakes: &HashMap<Pubkey, u64>
) -> HashMap<Pubkey, Vec<Pubkey>> where
    I: IntoIterator<Item = Pubkey>, 

remove redundant paths in the network

pub fn new_push_messages(
    &mut self,
    pending_push_messages: Vec<CrdsValue>,
    now: u64
) -> HashMap<Pubkey, Vec<CrdsValue>>

pub fn process_prune_msg(
    &self,
    self_pubkey: &Pubkey,
    peer: &Pubkey,
    destination: &Pubkey,
    origin: &[Pubkey],
    wallclock: u64,
    now: u64
) -> Result<(), CrdsGossipError>

add the from to the peer’s filter of nodes

pub fn refresh_push_active_set(
    &mut self,
    self_pubkey: &Pubkey,
    self_shred_version: u16,
    stakes: &HashMap<Pubkey, u64>,
    gossip_validators: Option<&HashSet<Pubkey>>,
    socket_addr_space: &SocketAddrSpace
)

refresh the push active set

• ratio - number of actives to rotate

pub fn new_pull_request(
    &self,
    thread_pool: &ThreadPool,
    self_keypair: &Keypair,
    self_shred_version: u16,
    now: u64,

    stakes: &HashMap<Pubkey, u64>,
    bloom_size: usize,
    ping_cache: &Mutex<PingCache>,
    pings: &mut Vec<(SocketAddr, Ping<[u8; 32]>)>,
    socket_addr_space: &SocketAddrSpace
) -> Result<(ContactInfo, Vec<CrdsFilter>), CrdsGossipError>

generate a random request

pub fn mark_pull_request_creation_time(&mut self, from: Pubkey, now: u64)

time when a request to from was initiated This is used for weighted random selection during new_pull_request It’s important to use the local nodes request creation time as the weight instead of the response received time otherwise failed nodes will increase their weight.

pub fn process_pull_requests<I>(&mut self, callers: I, now: u64) where
    I: IntoIterator<Item = CrdsValue>, 

process a pull request and create a response

pub fn generate_pull_responses(
    &self,
    thread_pool: &ThreadPool,
    filters: &[(CrdsValue, CrdsFilter)],
    output_size_limit: usize,
    now: u64
) -> Vec<Vec<CrdsValue>>

pub fn filter_pull_responses(
    &self,
    timeouts: &HashMap<Pubkey, u64>,
    response: Vec<CrdsValue>,
    now: u64,
    process_pull_stats: &mut ProcessPullStats
) -> (Vec<CrdsValue>, Vec<CrdsValue>, Vec<Hash>)

pub fn process_pull_responses(
    &mut self,
    from: &Pubkey,
    responses: Vec<CrdsValue>,
    responses_expired_timeout: Vec<CrdsValue>,
    failed_inserts: Vec<Hash>,
    now: u64,
    process_pull_stats: &mut ProcessPullStats
)

process a pull response

pub fn make_timeouts(
    &self,
    self_pubkey: Pubkey,
    stakes: &HashMap<Pubkey, u64>,
    epoch_duration: Duration
) -> HashMap<Pubkey, u64>

pub fn purge(
    &mut self,
    self_pubkey: &Pubkey,
    thread_pool: &ThreadPool,
    now: u64,
    timeouts: &HashMap<Pubkey, u64>
) -> usize
