Struct Simulation 

pub struct Simulation {
    pub nodes: Vec<GossipNode>,
    pub loss_rate: f64,
    /* private fields */
}

The simulation environment.

Fields

nodes: Vec<GossipNode>

Nodes in the simulation.

loss_rate: f64

Message loss rate (0.0 = no loss, 1.0 = all lost).

Implementations

impl Simulation

pub fn new(node_count: usize, seed: u64) -> Self

Create a new simulation with N nodes.

pub fn with_loss_rate(self, rate: f64) -> Self

Set message loss rate.

pub fn stats(&self) -> &SimStats

Get stats.

pub fn round(&self) -> u64

Current round.

pub fn step(&mut self)

Run one round of gossip: each node pings a random peer.

pub fn run_until_converged(&mut self, max_rounds: u64) -> Option<u64>

Run simulation until convergence or max rounds. Returns the round at which convergence was reached, or None.

pub fn add_constraint(&mut self, node_idx: usize, constraint: &str)

Add constraints to a specific node (simulate local operation).

pub fn record_satisfied(&mut self, node_idx: usize, count: u64)

Record satisfied constraints on a specific node.

pub fn is_converged(&self) -> bool

Check if all nodes have converged to the same state.

pub fn summary(&self) -> String

Print a summary of node states.
