Struct DeterministicEnv 

pub struct DeterministicEnv { /* private fields */ }

The four-knob deterministic bundle handed to a vector run.

Construct with DeterministicEnv::from_seed; pass clones into each party. The RNG is the only piece that must not be shared between parties — give each party its own fork via DeterministicEnv::fork so their streams diverge deterministically by party index.

Implementations

impl DeterministicEnv

pub fn from_seed(seed: u64) -> Self

Build an env rooted at seed. All forked RNGs derive from this.

pub fn seed(&self) -> u64

pub fn rng_for(&self, party_idx: usize) -> DeterministicRng

A fresh RNG for party idx. Mixing the party index into the seed means two parties never share a stream but the assignment is still deterministic for a given (env seed, roster).

pub fn fork(&self, party_idx: usize) -> ForkedEnv<'_>

Fork this env for a child party: shares the clock and memory counter (those are session-wide) but yields a party-specific RNG.

pub fn clock(&self) -> &DeterministicClock

pub fn memory(&self) -> &MemoryCounter

Trait Implementations

impl Debug for DeterministicEnv

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

Formats the value using the given formatter.
