Struct Xorshift 

pub struct Xorshift(/* private fields */);

Xorshift64 with Box–Muller normals. Deterministic and platform-independent.

Implementations

impl Xorshift

pub fn new(seed: u64) -> Self

A zero seed would make xorshift stick at zero, so it is remapped.

pub fn next_u64(&mut self) -> u64

pub fn uniform(&mut self) -> f64

Uniform on [0, 1) with 53 random bits.

pub fn normal(&mut self) -> f64

Standard normal via Box–Muller (one draw per call, cosine branch).

Trait Implementations

impl Clone for Xorshift

fn clone(&self) -> Xorshift

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Xorshift

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

Formats the value using the given formatter.
