Struct netstack3_core::testutil::FakeCryptoRng

pub struct FakeCryptoRng<R>(/* private fields */);

A wrapper which implements RngCore and CryptoRng for any RngCore.

This is used to satisfy [EventDispatcher]’s requirement that the associated Rng type implements CryptoRng.

Security

This is obviously insecure. Don’t use it except in testing!

Trait Implementations

impl<R: Clone> Clone for FakeCryptoRng<R>

fn clone(&self) -> FakeCryptoRng<R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R: Debug> Debug for FakeCryptoRng<R>

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

Formats the value using the given formatter.

impl Default for FakeCryptoRng<XorShiftRng>

fn default() -> FakeCryptoRng<XorShiftRng>

Returns the “default value” for a type.

impl<R: RngCore> RngContext for FakeCryptoRng<R>

type Rng<'a> = &'a mut FakeCryptoRng<R> where Self: 'a

The random number generator (RNG) provided by this RngContext.

fn rng(&mut self) -> Self::Rng<'_>

Gets the random number generator (RNG).

impl<R: RngCore> RngCore for FakeCryptoRng<R>

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<(), Error>

Fill dest entirely with random data.

impl<R: SeedableRng> SeedableRng for FakeCryptoRng<R>

type Seed = <R as SeedableRng>::Seed

Seed type, which is restricted to types mutably-dereferencable 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.
