Struct RandomFanout 

pub struct RandomFanout { /* private fields */ }

Random fanout gossip strategy

Selects a random subset of peers for each gossip round. This is the classic epidemic gossip approach.

Fanout Selection

• fanout=1: Minimal, slow convergence, lowest overhead
• fanout=2: Standard, O(log N) convergence, good balance
• fanout=3+: Fast convergence, higher overhead

For most HIVE deployments, fanout=2 is recommended.

Implementations

impl RandomFanout

pub fn new(fanout: usize) -> Self

Create a new random fanout strategy

Arguments

• fanout - Number of peers to select per gossip round

pub fn with_seed(fanout: usize, seed: u64) -> Self

Create with a fixed seed for deterministic testing
