Struct ReplicateSeedDeriver 

pub struct ReplicateSeedDeriver { /* private fields */ }

Lazy source of deterministic, order-independent named replicate seeds.

A namespace identifies one scientific random stream, such as matrix, pairing, or replacement/task-17. The same base seed, replicate index, and namespace always produce the same value regardless of process, scheduling, or request order. Different namespaces are domain-separated.

Implementations

impl ReplicateSeedDeriver

pub const fn new(base_seed: u64, replicate_index: u64) -> Self

Creates a lazy deriver for one replicate.

pub const fn base_seed(self) -> u64

Returns the study-level base seed.

pub const fn replicate_index(self) -> u64

Returns the zero-based replicate index.

pub fn derive(self, namespace: &str) -> Result<DerivedSeed, RngRecordError>

Derives one named stream seed and its matching provenance record.

Derivation occurs only when requested. The namespace must be nonblank and should remain stable across executions. The versioned byte contract is SHA-256 over the method version, base seed, replicate index, namespace byte length, and namespace bytes; the first eight digest bytes are read as a big-endian u64.
