Struct ScriptedRng 

pub struct ScriptedRng { /* private fields */ }

A bounded deterministic RNG that returns a caller-supplied sequence of u64 samples.

Each u32 consumes one sample and returns its low 32 bits. Byte fills encode samples in little-endian order and discard unused bytes from the final sample.

Sampling beyond the supplied sequence panics.

Implementations

impl ScriptedRng

pub fn new(samples: impl IntoIterator<Item = u64>) -> Self

Creates a bounded RNG from the provided samples.

Trait Implementations

impl Debug for ScriptedRng

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

Formats the value using the given formatter.

impl From<ScriptedRng> for Box<dyn CryptoRng + Send + 'static>

Available on neither commonware_stability_BETA nor commonware_stability_DELTA nor commonware_stability_EPSILON nor commonware_stability_GAMMA nor commonware_stability_RESERVED.

Boxes the rng for runtimes that take a dynamic rng (e.g. the deterministic runtime’s Config::with_rng).

fn from(rng: ScriptedRng) -> Self

Converts to this type from the input type.

impl TryCryptoRng for ScriptedRng

Available on neither commonware_stability_BETA nor commonware_stability_DELTA nor commonware_stability_EPSILON nor commonware_stability_GAMMA nor commonware_stability_RESERVED.

impl TryRng for ScriptedRng

Available on neither commonware_stability_BETA nor commonware_stability_DELTA nor commonware_stability_EPSILON nor commonware_stability_GAMMA nor commonware_stability_RESERVED.

type Error = !

The type returned in the event of a RNG error.

fn try_next_u32(&mut self) -> Result<u32, Self::Error>

Return the next random u32.

fn try_next_u64(&mut self) -> Result<u64, Self::Error>

Return the next random u64.

fn try_fill_bytes(&mut self, dest: &mut [u8]) -> Result<(), Self::Error>

Fill dst entirely with random data.
