Implementations

impl CrdsGossipPull

pub fn new_pull_request(
    &self,
    thread_pool: &ThreadPool,
    crds: &Crds,
    self_id: &Pubkey,
    self_shred_version: u16,
    now: u64,
    gossip_validators: Option<&HashSet<Pubkey>>,
    stakes: &HashMap<Pubkey, u64>,
    bloom_size: usize
) -> Result<(Pubkey, Vec<CrdsFilter>, CrdsValue), 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 record_old_hash(&mut self, hash: Hash, timestamp: u64)

Store an old hash in the purged values set

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

process a pull request

pub fn generate_pull_responses(
    &self,
    crds: &Crds,
    requests: &[(CrdsValue, CrdsFilter)],
    output_size_limit: usize,
    now: u64
) -> Vec<Vec<CrdsValue>>

Create gossip responses to pull requests

pub fn filter_pull_responses(
    &self,
    crds: &Crds,
    timeouts: &HashMap<Pubkey, u64>,
    responses: Vec<CrdsValue>,
    now: u64,
    stats: &mut ProcessPullStats
) -> (Vec<VersionedCrdsValue>, Vec<VersionedCrdsValue>, Vec<Hash>)

pub fn process_pull_responses(
    &mut self,
    crds: &mut Crds,
    from: &Pubkey,
    responses: Vec<VersionedCrdsValue>,
    responses_expired_timeout: Vec<VersionedCrdsValue>,
    failed_inserts: Vec<Hash>,
    now: u64,
    stats: &mut ProcessPullStats
) -> Vec<(CrdsValueLabel, Hash, u64)>

process a vec of pull responses

pub fn purge_failed_inserts(&mut self, now: u64)

pub fn build_crds_filters(
    &self,
    thread_pool: &ThreadPool,
    crds: &Crds,
    bloom_size: usize
) -> Vec<CrdsFilter>

    self_id: &Pubkey,
    stakes: &HashMap<Pubkey, u64>,
    epoch_ms: u64,
    min_ts: u64
) -> HashMap<Pubkey, u64>

pub fn make_timeouts(
    &self,
    self_id: &Pubkey,
    stakes: &HashMap<Pubkey, u64>,
    epoch_ms: u64
) -> HashMap<Pubkey, u64>

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

Purge values from the crds that are older then active_timeout The value_hash of an active item is put into self.purged_values queue

pub fn purge_purged(&mut self, min_ts: u64)

Purge values from the self.purged_values queue that are older then purge_timeout
