Enum InterpreterRng

Source

pub(crate) enum InterpreterRng {
    Fast(SmallRng),
    Deterministic(Box<ChaCha20Rng>),
}

Expand description

Selectable RNG backend for the interpreter.

Fast (default) uses SmallRng (Xoshiro256++) — fast, non-cryptographic, suitable for R’s statistical RNG. Deterministic uses ChaCha20 — slower but produces identical sequences across all platforms and Rust versions, which is important for cross-platform reproducibility.
