Struct ExperimentSeed 

pub struct ExperimentSeed {
    pub master_seed: u64,
    pub component_seeds: HashMap<String, u64>,
    pub ieee_strict: bool,
}

Seed management for reproducible experiments.

Implements EDD-03: Deterministic Reproducibility.

let seed = ExperimentSeed::new(42);
let arrival_rng = seed.derive_rng("arrivals");
let service_rng = seed.derive_rng("service");

Fields

master_seed: u64

Master seed for all RNG operations

component_seeds: HashMap<String, u64>

Per-component seeds derived from master

ieee_strict: bool

IEEE 754 strict mode for floating-point reproducibility

Implementations

impl ExperimentSeed

pub fn new(master_seed: u64) -> Self

Create a new experiment seed.

pub fn relaxed(self) -> Self

Disable IEEE strict mode (for performance).

pub fn with_component(self, component: &str, seed: u64) -> Self

Pre-register a component seed.

pub fn derive_seed(&self, component: &str) -> u64

Derive a seed for a specific component.

Uses deterministic derivation from master seed if not pre-registered.

Trait Implementations

impl Clone for ExperimentSeed

fn clone(&self) -> ExperimentSeed

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExperimentSeed

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
