Implementations§

Source§

impl Simulator

Source

pub fn new( simulator_config: SimulatorConfig, network_config: impl Into<NetworkConfig>, ) -> Self

Creates a new simulator.

Source

pub fn rng(&mut self) -> ChaCha12Rng

Creates a new random number generator, derived from the simuator’s RNG.

Source

pub fn random_peer(&mut self) -> u64

Returns the peer id of a random peer.

Source

pub fn peer_count(&self) -> usize

Returns the number of peers.

Source

pub fn remove_peers(&mut self, n: usize)

Removes n peers from the network.

Source

pub fn report(&mut self) -> NetworkReport<u64>

Returns a report on the current state of the network.

Source

pub fn bootstrap(&mut self, bootstrap_mode: BootstrapMode) -> NetworkReport<u64>

Bootstraps the network.

See BootstrapMode for details.

Returns the NetworkReport after finishing the bootstrap.

Source

pub fn gossip_round(&mut self, messages: Vec<(u64, Bytes)>) -> usize

Runs a round of gossiping.

messages is a list of (sender, message) pairs. All messages will be sent simultaneously. The round will run until all peers received all messages, or until SimulatorConfig::gossip_round_timeout is elapsed.

Returns the number of undelivered messages.

Source

pub fn round_stats_average(&self) -> RoundStatsAvg

Calculates the RoundStatsAvg of all gossip rounds.
