Struct RngWide 

pub struct RngWide { /* private fields */ }

Available on not ((x86 or x86-64) and (target features sse2 or avx2 or avx512f)).

Implements RomuTrio with 512-bit width.

Implementations

impl RngWide

pub fn new() -> Self

Available on non-crate feature unstable_simd only.

Creates a new RngWide with a seed from the best available randomness source.

pub const fn from_seed_with_64bit(seeds: [u64; 8]) -> Self

Available on non-crate feature unstable_simd only.

Creates a new RngWide from the given eight 64-bit seeds.

The seeds should be from a high randomness source.

pub const fn from_seed_with_192bit(seeds: [[u64; 3]; 8]) -> Self

Available on non-crate feature unstable_simd only.

Creates a new RngWide from the given eight 192-bit seeds.

The seeds should be from a high randomness source.

If the seeds are of low quality, user should call RngWide::mix() to improve the quality of the first couple of random numbers.

Notice

The variables must be seeded such that at least one bit of state is non-zero.

pub fn mix(&mut self)

Available on non-crate feature unstable_simd only.

Mixes the states, which should improve the quality of the random numbers.

Should be called when having (re-)seeded the generator with a fixed value of low randomness.

pub fn seed(&mut self)

Available on non-crate feature unstable_simd only.

Re-seeds the RngWide from the best available randomness source.

pub fn u64x8(&mut self) -> [u64; 8]

Available on non-crate feature unstable_simd only.

Generates eight random u64 values.

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

Available on non-crate feature unstable_simd only.

Fills a mutable [u8] slice with random values.

Trait Implementations

impl Default for RngWide

Available on non-crate feature unstable_simd only.

fn default() -> Self

Returns the “default value” for a type.
