Struct SimulationBuilder 

pub struct SimulationBuilder { /* private fields */ }

Builder for configuring and constructing a simulation.

Use the builder methods to add process pools, set network topology, configure bandwidth, choose an execution mode (single-threaded or parallel), and finally call SimulationBuilder::build to obtain a runnable simulation.

Implementations

impl SimulationBuilder

pub fn add_pool<P: ProcessHandle + Default + Send + 'static>( self, name: &str, size: usize, ) -> SimulationBuilder

Creates a named pool of size processes of type P. Every process is also added to GLOBAL_POOL.

pub fn seed(self, seed: u64) -> Self

Sets the random seed for deterministic execution.

pub fn time_budget(self, time_budget: Jiffies) -> Self

Sets the maximum simulation duration. The simulation stops when this time is reached.

pub fn within_pool_latency(self, pool: &str, distr: Distributions) -> Self

Configures latency between processes within the same named pool.

pub fn between_pool_latency( self, from: &str, to: &str, distr: Distributions, ) -> Self

Configures latency between processes in two different pools (symmetric).

pub fn vnic_bandwidth(self, bandwidth: BandwidthConfig) -> Self

Configures per-process NIC bandwidth limits.

pub fn simple(self) -> Self

Selects single-threaded execution mode (default).

pub fn parallel(self, threads: Threads) -> Self

Selects parallel execution mode using the given number of worker threads.

pub fn build(self) -> Box<dyn SimulationRunner>

Finalizes configuration and builds the simulation runner.

Trait Implementations

impl Default for SimulationBuilder

fn default() -> Self

Returns the “default value” for a type.
