Struct chain_crypto::testing::TestCryptoRng

pub struct TestCryptoRng(SmallRng);

A faster non-cryptographic RNG to be used in tests. NOTE: this RNG does implement CryptoRng, but it is not really cryptographic. It MUST NOT be used in the production code.

Trait Implementations

impl RngCore for TestCryptoRng

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

Return the next random u64.

fn fill_bytes(&mut self, dest: &mut [u8])

Fill dest with random data.

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

Fill dest entirely with random data.

impl SeedableRng for TestCryptoRng

type Seed = <SmallRng as SeedableRng>::Seed

Seed type, which is restricted to types mutably-dereferenceable as u8 arrays (we recommend [u8; N] for some N).

fn from_seed(seed: Self::Seed) -> Self

Create a new PRNG using the given seed.

fn seed_from_u64(state: u64) -> Self

Create a new PRNG using a u64 seed.

fn from_rng<R>(rng: R) -> Result<Self, Error>where R: RngCore,

Create a new PRNG seeded from another Rng.

fn from_entropy() -> Self

Creates a new instance of the RNG seeded via getrandom.
