Struct Philox 

pub struct Philox { /* private fields */ }

Philox 4x32-10 counter-based pseudo-random number generator.

This generator natively supports stream IDs, making it ideal for parallel generation. Each (seed, stream_id) pair produces an independent, non-overlapping output sequence.

Example

use ferray_random::bitgen::Philox;
use ferray_random::bitgen::BitGenerator;

let mut rng = Philox::seed_from_u64(42);
let val = rng.next_u64();

Trait Implementations

impl BitGenerator for Philox

fn next_u64(&mut self) -> u64

Generate the next 64-bit unsigned integer.

fn seed_from_u64(seed: u64) -> Self

Create a new generator seeded from a single u64.

fn jump(&mut self) -> Option<()>

Advance the generator state by a large step (2^128 for Xoshiro256**).

fn stream(seed: u64, stream_id: u64) -> Option<Self>

Create a new generator from a seed and a stream ID.

fn next_f64(&mut self) -> f64

Generate a uniformly distributed f64 in [0, 1).

fn next_f32(&mut self) -> f32

Generate a uniformly distributed f32 in [0, 1).

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

Fill a byte slice with random bytes.

fn next_u64_bounded(&mut self, bound: u64) -> u64

Generate a u64 in the range [0, bound) using rejection sampling.

impl Clone for Philox

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
