Struct nanorand::rand::pcg64::Pcg64

pub struct Pcg64 { /* fields omitted */ }

An instance of the Pcg64 random number generator.
Seeded from the system entropy generator when available.
This generator is NOT cryptographically secure.

Implementations

impl Pcg64

pub fn new() -> Self

Create a new Pcg64 instance, seeding from the system's default source of entropy.

pub fn new_seed(seed: u128) -> Self

Create a new Pcg64 instance, using a provided seed.

Trait Implementations

impl Clone for Pcg64

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Pcg64

fn default() -> Self

Create a new Pcg64 instance, seeding from the system's default source of entropy.

impl Display for Pcg64

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

Formats the value using the given formatter.

impl RNG for Pcg64

type Output = [u8; 8]

The byte output that this RNG emits.

fn rand(&mut self) -> Self::Output

Generates a random sequence of bytes, seeding from the internal state.

fn rand_with_seed(_seed: &[u8]) -> Self::Output

Generates a random sequence of bytes, with a custom seed.

fn reseed(&mut self, new_seed: &[u8])

Reseeds the RNG using a custom seed.

fn generate<R: RandomGen<Self>>(&mut self) -> R

Generates a random of the specified type, seeding from the internal state.

fn generate_range<R: RandomRange<Self>>(&mut self, lower: R, upper: R) -> R

Generates a random of the specified type, seeding from the internal state.

fn shuffle<I, S: AsMut<[I]>>(&mut self, target: S)

Shuffle a slice, using the RNG.

impl Zeroize for Pcg64

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not "optimized away" by the compiler.
