Struct SeededSampler 

pub struct SeededSampler { /* private fields */ }

A public deterministic sampler with explicit version, work, state and forks.

fork(label) is domain-separated from both the root stream and other labels; it never consumes its parent. Existing consumers use the root stream and thus retain their historical SplitMix64-v1 output exactly.

Implementations

impl SeededSampler

pub fn new(seed: u64) -> Self

Constructs an unbounded root stream. Algorithms should preflight their own exact work or use Self::with_max_words for refusal.

pub fn with_max_words(seed: u64, max_words: u64) -> Self

Constructs a root stream that refuses generation beyond max_words.

pub fn replay(receipt: SamplerReceipt) -> Self

Restores a canonical state and word allowance.

pub fn receipt(&self) -> SamplerReceipt

Captures a replay receipt.

pub fn fork(&self, label: u64) -> Self

Returns an independent, deterministic labeled substream without advancing this stream.

pub fn try_next_u64(&mut self) -> Result<u64, DesignError>

Produces the next word, refusing when the declared allowance is spent.

pub fn unit_interval(&mut self) -> f64

Maps one word to [0, 1) using the stable 53-bit convention.
