Struct AesRng

pub struct AesRng(/* private fields */);

This uses AES in a counter-mode to implement a PRG. TODO: Citation for why/when this is secure.

Implementations

impl AesRng

pub fn new() -> Self

Create a new random number generator using a random seed from rand::random.

pub fn fork(&mut self) -> Self

Create a new RNG using a random seed from this one.

Trait Implementations

impl Clone for AesRng

fn clone(&self) -> AesRng

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AesRng

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

Formats the value using the given formatter.

impl Default for AesRng

fn default() -> Self

Returns the “default value” for a type.

impl From<AesRngCore> for AesRng

fn from(core: AesRngCore) -> Self

Converts to this type from the input type.

impl RngCore for AesRng

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.

impl SeedableRng for AesRng

type Seed = Block

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(rng: &mut impl RngCore) -> Self

Create a new PRNG seeded from an infallible Rng.

fn try_from_rng<R>(rng: &mut R) -> Result<Self, <R as TryRngCore>::Error>

where R: TryRngCore,

Create a new PRNG seeded from a potentially fallible Rng.

fn from_os_rng() -> Self

Creates a new instance of the RNG seeded via getrandom.

fn try_from_os_rng() -> Result<Self, Error>

Creates a new instance of the RNG seeded via getrandom without unwrapping potential getrandom errors.
