Struct GossipState

Source

pub struct GossipState {
    pub seen: HashMap<String, u64>,
}

Expand description

Tracks the highest sequence number seen from each peer to deduplicate messages.

Fields§

§seen: HashMap<String, u64>

Maps peer_id → highest sequence observed so far.

Implementations§

Source §

impl GossipState

Source

pub fn is_new(&self, peer_id: &str, sequence: u64) -> bool

Returns true when sequence is strictly greater than the last recorded value for peer_id (or when the peer has never been seen).

Source

pub fn record(&mut self, peer_id: &str, sequence: u64)

Advance (or initialise) the tracked sequence for peer_id. Only updates when sequence is greater than the currently stored value.

Source

pub fn prune_stale(&mut self, threshold_seq: u64)

Remove all peers whose highest recorded sequence is ≤ threshold_seq. Useful for cleaning up stale entries from long-gone peers.
