Struct libafl::bolts::rands::Lehmer64Rand

pub struct Lehmer64Rand { /* fields omitted */ }

XXH3 Based, hopefully speedy, rnd implementation

Implementations

impl Lehmer64Rand

pub fn with_seed(seed: u64) -> Self

Creates a new Lehmer rand with the given seed

Trait Implementations

impl Clone for Lehmer64Rand

fn clone(&self) -> Lehmer64Rand

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Lehmer64Rand

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

Formats the value using the given formatter.

impl Default for Lehmer64Rand

A default RNG will usually produce a nondeterministic stream of random numbers. As we do not have any way to get random seeds for no_std, they have to be reproducible there. Use [$rand::with_seed] to generate a reproducible RNG.

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Lehmer64Rand

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Rand for Lehmer64Rand

fn set_seed(&mut self, seed: u64)

Sets the seed of this Rand

fn next(&mut self) -> u64

Gets the next 64 bit value

fn below(&mut self, upper_bound_excl: u64) -> u64

Gets a value below the given 64 bit val (inclusive)

fn between(&mut self, lower_bound_incl: u64, upper_bound_incl: u64) -> u64

Gets a value between the given lower bound (inclusive) and upper bound (inclusive)

fn choose<I, E, T>(&mut self, from: I) -> T where
    I: IntoIterator<Item = T, IntoIter = E>,
    E: ExactSizeIterator + Iterator<Item = T>, 

Choose an item at random from the given iterator, sampling uniformly.

impl RandomSeed for Lehmer64Rand

fn new() -> Self

Creates a rand instance, pre-seeded with the current time in nanoseconds.

impl Serialize for Lehmer64Rand

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
